Make the `hex` dependency optional. This means not implementing
`Display` for some types if `hex` is not enabled and only implementing
`Debug`.
Also without `hex` enabled:
- We loose the ability to parse an `OutPoint` from string because we
can no longer parse `Txid`.
- We loose the hex formatting of witness elements.
Note also that `primitives` builds with the `serde` feature even if
`hex?/serde` is excluded from the `serde` feature. I found this
surprising.
We have the `hex_lit` dependency for converting a hex string literal
to an array.
Currently we have a `test_hex_unwrap` macro in the `hex v0.3.0` release
but not on either `master` or the upcoming `v1.0.0-alpha.0` release.
This is making PRs around releasing and depending on the release more
noisy than required.
Use `hex_lit::hex` where possible (often needing an additional call to
`to_vec()`) and where not possible use `Vec::from_hex`.
We can use `deserialize_hex` when outside of the actual benchmark code
to simplify the functions.
Also add an additional test that benchmarks `deserialize_hex`.

InputWeightPrediction can be used to determine the weight needed
to calculate the effective_value. This simplifies the process for api
consumers by allowing an easier interface with which to use to predict
the weight. Prior to this change, it was required to manually calculate
the predicted weight for whichever input type was to be used.
ebaf162a96 Add push_relative_lock_time() and deprecate push_sequence() (Erick Cestari)
Pull request description:
This pr improves the script builder API to better align with Bitcoin semantics when working with relative timelocks:
- Add `push_relative_lock_time()` method that takes a `relative::LockTime` parameter, which correctly represents the semantic meaning when working with CHECKSEQUENCEVERIFY
- Deprecate `push_sequence()` in favor of `push_relative_lock_time()` to avoid confusion between sequence numbers and relative timelocks
This addresses a potential confusion point in the API where developers might incorrectly push raw sequence numbers in scripts when what they actually need is to push a relative locktime value that will be checked against the transaction's sequence numbers by CHECKSEQUENCEVERIFY.

The type returned by `Witness::taproot_control_block()` was just `&[u8]`
which wasn't very nice since users then had to manually decode it which
so far also required allocation. Thanks to previous improvements to
`ControlBlock` it is now possible to return a `ControlBlock` type
directly.
To avoid expensive checks, this change adds a new type
`SerializedXOnlyPublicKey` which is a wrapper around `[u8; 32]` that is
used in `ControlBlock` if complete checking is undesirable. It is then
used in the `ControlBlock` returned from
`Witness::taproot_control_block`. Users can still conveniently validate
the key using `to_validated` method.
It then uses this type in the recently-added `P2TrSpend` type. As a side
effect this checks more properties of `Witness` when calling unrelated
methods on `Witness`. From correctness perspective this should be OK: a
witness obtained from a verified source will be correct anyway and, if
these checks were done by the caller, they can be removed.
From performance perspective, if the `Witness` was obtained from a
verified source (e.g. using Bitcoin Core RPC) these checks are wasted
CPU time. But they shouldn't be too expensive, we already avoid
`secp256k1` overhead and, given that they always succeed in such case,
they should be easy to branch-predict.
Since the introduction of `Script` `unsafe` started slowly creeping in
as more types with similar semantics were added. The `unsafe` in these
cases is just for trivial conversions between various pointer-like
types. As such, it's possible to move these into a single macro that
takes care of the conversions at one place and avoid repeating the same
`unsafe` code in the codebase. This decreases the cost of audits which
now only need to happen in `internals`, focuses any changes to happen in
that single macro and decreases the chance that we will mess up
similarly to the recent `try_into().expect()` issue (but this time with
UB rather than panic).
The new macro accepts syntax very similar to the already-existing struct
declarations with these differences:
* The struct MUST NOT have `#[repr(transparent)]` - it's added by the
macro
* If the struct uses `PhantomData` it must be the first field and the
real data must be the second field (to allow unsized types).
* The struct must be immediately followed by an impl block containing at
least on conversion function.
* If the struct has generics the impl block has to use the same names of
generics.
* The conversion functions don't have bodies (similarly to required
trait methods) and have a fixed set of allowed signatures.
* Underscore (`_`) must be used in place of the inner type in the
conversion function parameters.
The existing code can simply call the macro with simple changes and get
the same behavior without any direct use of `unsafe`. This change
already calls the macro for all relevant existing types. There are still
some usages left unrelated to the macro, except one additional
conversion in reverse direction on `Script`. It could be moved as well
but since it's on a single place so far it's not really required.

e744347022 Make usage of Self and type uniform across both modules (Erick Cestari)
dfb49f014c Rename impl_try_from_array to impl_from_array (Erick Cestari)
Pull request description:
This PR makes two main changes:
1. Standardizes the function signatures in the `Amount` and `SignedAmount` implementations by consistently using `Self` as the return type instead of the concrete type names. This improves code consistency, maintainability, and follows Rust's idiomatic practices.
2. Renames `impl_try_from_array` to `impl_from_array` to better reflect its functionality.
### Changes
**Consistent usage of Self instead of concrete types**
- Replace all occurrences of `-> Amount` with `-> Self `in unsigned.rs
- Replace all occurrences of `-> SignedAmount` with `-> Self` in signed.rs
- Make similar replacements for Option/Result return types
- Use `Self::` instead of explicit type name for static method calls
**Function rename**
Renamed `impl_try_from_array` to `impl_from_array` for better clarity

069d2fd07e Add XOnlyPublicKey support for PSBT key retrieval and improve Taproot signing (Erick Cestari)
Pull request description:
The `bip32_sign_schnorr` function was previously only attempting to retrieve private keys using `KeyRequest::Bip32`, which limited the ability to sign Taproot inputs with key maps that don't support BIP32 derivation paths.
## Changes
- Added new `KeyRequest::XOnlyPubkey` variant to support direct retrieval using XOnly public keys
- Implemented `GetKey` for `HashMap<XOnlyPublicKey, PrivateKey>` for more efficient Taproot key management
- Modified `HashMap<PublicKey, PrivateKey>` implementation to handle XOnlyPublicKey requests by checking both even and odd parity variants
- Added comprehensive tests for both key map implementations
These improvements enable wallet implementations to store keys indexed by either `PublicKey` or `XOnlyPublicKey` and successfully sign PSBTs.

There's a restriction that for structs containing unsized types the
unsized type has to be the last field. `Address` is not an unsize type
but we are going to introduce a macro that will assume this order to
work equally well with both sized and unsized types. Thus we swap it
upfront here.
The `Witness`-related tests were constructing `Witness` in
over-complicated way by serializing `Vec<Vec<u8>>` and then
deserializing `Witness` even though they were not supposed to test
serialization but Taproot accessor methods. This was difficult to
understand and maintain.
This change simplifies them to just construct the `Witness` from array
of `Vec<u8>`s using the recently-added constructors. Note that we
already have serialization tests written separately so we're not losing
meaningful coverage here.

These are defined in the BIP as invalid. The previous commit fixed a bug
where invalid key was parsed as valid and this bug can be caught by
these vectors. Therefore, if this commit is ordered before the last one
the test will fail.
Previously we've used `try_into().expect()` because const generics were
unavailable. Then they became available but we didn't realize we could
already convert a bunch of code to not use panicking conversions. But we
can (and could for a while).
This adds an extension trait for arrays to provide basic non-panicking
operations returning arrays, so they can be composed with other
functions accepting arrays without any conversions. It also refactors a
bunch of code to use the non-panicking constructs but it's certainly not
all of it. That could be done later. This just aims at removing the
ugliest offenders and demonstrate the usefulness of this approach.
Aside from this, to avoid a bunch of duplicated work, this refactors
BIP32 key parsing to use a common method where xpub and xpriv are
encoded the same. Not doing this already led to a mistake where xpriv
implemented some additional checks that were missing in xpub. Thus this
change also indirectly fixes that bug.

This also intentionally does **not** address decoding of `ControlBlock` from `Witness` since I'm not sure about the API.
Rationale for doing the `Buf` rename: while doing it with `Script` was very painful it shouldn't be here since it's not used that often and also we can just backport the first commit with deprecated type alias. I was thinking of having `TaprootMerkleBr` but it'd be inconsistent and the name is silly.
(Also if anyone is wondering why I did this: I was too exhausted to do more important stuff but felt like doing something nice and easy like this.)

We have a ton of calls to `from_sat_unchecked` for small constants which
were clearly in range, e.g. in fee.rs. Add a new constfn for these
cases. Don't bother making a generic Into<u32>/Into<u16> variant because
there isn't an obvious name for it.
There are 7 instances where we're using this method with values that are
out of range, which we leave as from_sat_unchecked for now.
The new unsized type is more flexible and so are the references to it.
Just like we pass around `&str` instead of `&String` we should be
passing `&TaprootMerkleBranch` instead of `&TaprootMerkleBranchBuf`.
`TaprootMerkleBranchBuf` previously derefed to a slice which lost the
information about length being valid. This commit changes the type
which, while API-breaking, is not disruptive because the type has API
very similar to slice.
`TaprootMerkleBranchBuf` being a vec introduced intermediate allocation
when creating or decoding `Witness`. However the representation on the
wire is the same as in-memory (aside from `#[repr(transparent)]`) so
this allocation wasn't really needed.
This commit introduces `TaprootMerkleBranch` type which is unsized and
can be used in place of `TaprootMerkleBranchBuf` within `ControlBlock`.
Aside from removing the intermediate allocation, this improves the API a
bit: the conversion from array to other type is no longer needed because
it's performed by `ControlBlock` in its methods. Thus, consumers who
have an array can simply set it as `merkle_branch` field and then encode
the `ControlBlock` into witness. A convenience method is also provided
to push the `ControlBlock` along with other parts at the end of the
`Witness`.

Enforcing the MAX_MONEY invariant is quite involved because it means
multiple things:
- Constructing amounts is now fallible
- Converting from unsigned to signed is now infallible
- Taking the absolute value is now infallible
- Integer overflow is illuminated in various places
Details:
- Update from_sat to check the invariant
- Fix all docs including examples
- Use the unchecked constructor in test code
- Comment any other use of the unchecked constructor
- Deprecate unchecked_abs

8f74b823ab Add validation for private key format and master key constraints (Erick Cestari)
Pull request description:
This PR addresses issue #4195 by adding proper validation when decoding extended private keys:
### Changes
- Add validation to ensure byte 45 is zero as required by BIP-32 specification for private keys
- For master keys (depth=0), add validation to ensure parent fingerprint is zero
- For master keys (depth=0), add validation to ensure child number is zero
- Add corresponding error types to handle these validation failures
- Add unit tests to verify each validation rule
### Validation Rationale
These checks improve security by rejecting malformed extended keys that could potentially lead to unexpected behavior. As noted in the issue discussion, these validations are explicitly required by the BIP-32 specification.
### Testing
Added three new unit tests to verify each validation rule:
- test_reject_xpriv_with_non_zero_byte_at_index_45
- test_reject_xpriv_with_zero_depth_and_non_zero_index
- test_reject_xpriv_with_zero_depth_and_non_zero_parent_fingerprint
Fixes#4195

e4513bf925 feat: add MAX_BLOCK_SERIALIZED_SIZE existing in core (ChrisCho-H)
Pull request description:
fad0d9ea2d1e807806fa141238e279fddea6ae99: add `MAX_BLOCK_SERIALIZED_SIZE` as constant, which also exists in [bitcoin-core](59ff17e5af/src/consensus/consensus.h (L13)).
I originally thought it would be better to use this value for checking limit of push_bytes [here](0870cd1660/bitcoin/src/blockdata/script/push_bytes.rs (L31)), as it's the actual limit(`OP_PUSHDATA4` semantic says it could allow up to 4GB though). However, I'm not sure whether there might be need to push_bytes larger than `MAX_BLOCK_SERIALIZED_SIZE`, so just let developer use this constant to check the actual limit rather than enforcing it.

a65d1d8b95 docs: Update README to replace use of mutagen with cargo-mutants (AM)
Pull request description:
Hey there!
I am just getting up to speed with the project and in following the README discovered that there are still references to the previous mutation testing tool `mutagen`. I updated the README to refer to the new tool, `cargo-mutation`.
I'm suggesting the user use the same command, `cargo mutants --in-place --no-shuffle`, as is run in the weekly CI workflow.
I noticed that there are still references to the old `mutate` attribute in the following files. I removed these as well as per [feedback](https://github.com/rust-bitcoin/rust-bitcoin/pull/4228#issuecomment-2709407253).
`primitives/Cargo.toml`:
```
[lints.rust]
unexpected_cfgs = { level = "deny", check-cfg = ['cfg(mutate)'] }
```
and
`bitcoin/Cargo.toml`:
```
unexpected_cfgs = { level = "deny", check-cfg = ['cfg(bench)', 'cfg(fuzzing)', 'cfg(kani)', 'cfg(mutate)'] }
```
Update to PR: removed incorrect understanding of logic in PR description as per [feedback](https://github.com/rust-bitcoin/rust-bitcoin/pull/4228#issuecomment-2709408598) and removed `cfg(mutate)` from above 2 files.

Calculating the minimum non-dust fee currently panics if either the
script is really big or the dust fee rate is really big.
Harden the API by returning an `Option` instead of panicing.
This commit adds additional validation checks when decoding extended private keys:
1. Verifies that byte 45 is zero as required by BIP-32 specification
2. For master keys (depth=0), ensures parent fingerprint is zero
3. For master keys (depth=0), ensures child number is zero
These checks improve security by rejecting malformed keys that could
potentially lead to unexpected behavior. Added corresponding error types
and unit tests to verify each validation rule.

a013700527 Replace uses of `chunks_exact` with `as_chunks` (Martin Habovstiak)
Pull request description:
This is now ready for review.
In the past we've been using `chunks_exact` because const generics were unstable but then, when they were stabilized we didn't use `as_chunks` (or `array_chunks`) since they were unstable. But the instability was only because Rust devs don't know how to handle `0` being passed in. The function is perfectly implementable on stable. (With a tiny, easy-to-understand `unsafe` block.) `core` doesn't want to make a decision for all other crates yet but we can make it for our own crates because we know that we simply never pass zero. (And even if we did, we could just change the decision.)
It also turns out there's a hack to simulate `const {}` block in our MSRV, so we can make compilation fail early.
This commit adds an extension trait to internals to provide the methods, so we no longer have to use `chunks_exact`. It also cleans up the code quite nicely.
Previous unresolved question, leaving for reference:
> One issue with this change is that the names collide which could lead to hard error in future Rust versions. How do we solve it?
> * ignore and just backport the fix once that actually happens
> * rename the methods to something reasonable (e.g. `as_array_chunks`) - this risks that they'll rename the methods to the same thing by accident and it'll break anyway
> * rename the methods to something silly (`bitcoin_as_chunks`) - yeah, the risk above is not there but then we have silly-looking code.
We've decide to just rename the methods to something that won't possibly collide.

We just re-named `Timestamp` to `BlockTime`. We have a `units::block`
module but it currently holds abstractions (`BlockHeight` and
`BlockInterval`) that are not onchain abstractions and therefore
somewhat different from the `BlockTime`. Instead of making `block` a
block 'utils' module instead re-name the `timestamp` module to `time`.
We just added a `Timestamp` type without knowing that there was a push
by OpenTimestamps to also create a timestamp and that our new type may
lead to confusion. Our timestamp is explicitly for the `time` field in a
block so we can call it `BlockTime`. This name change makes the module
name stale but we will change that in a following patch to ease review.

Pull request description:
The `hex` crate is not always desirable - e.g. when the consumer wants to work with raw data only. We already had this optional in `hashes` but if `hashes` is going to depend on `internals` it would break this property.

- Changed both functions to accept S as a value (FnMut) instead of &mut S
- Removes need to annotate &mut when calling the function
Add a standalone `hash` function that is a drop in replacement for
`GeneralHash::hash`. Do not add it to `hmac` - this is in parity with
the current code because `Hmac` does not implement `GeneralHash::hash`.
Use the new function in `bitcoin` removing all occurrences of
`GeneralHash` from `bitcoin`.
In `hashes` replace usage of `GeneralHash::hash` with the new `hash`
function.
We would like to do away with the `GeneralHash` trait. Currently we
bound `Hmac` and `HmacEngine` on it but this is unnecessary now that we
have added `HashEngine::finalize` and `HashEngine::Hash`.
Bound the `HmacEngine` on `HashEngine` (which has an associated `Hash`
type returned by `finilalize`).
Bound `Hmac` type on `T::Hash` where `T` is `HashEngine`.
Includes some minor shortening of local variable names around hmac
engine usage.
Note this means that `Hmac` no longer implements `GeneralHash`.

During upgrade of `secp256k1` a number of function calls needed to be
rewritten to not use `from_slice` but `from_byte_array`. Unfortunately,
the conversion wasn't correct and caused panics on invalid inputs
rather than errors.
This fixes it simply by calling `try_into` on the entire slice and
converting the error.

Since arrays better convey the intention than slices when parsing
fixed-sized bytes we're migrating to them. This deprecates the
`from_slice` method similarly to how we do it elsewhere.
Private keys have statically-known length of 32 bytes and we are
migrating types with known lenths to use `from_byte_array` methods. This
adds the method to `PrivateKey` as well and uses it to implement
`from_slice`.
During upgrade of `secp256k1` a number of function calls needed to be
rewritten to not use `from_slice` but `from_byte_array`. Unfortunately,
the conversions wasn't correct and caused panics on invalid inputs
rather than errors.
This fixes it simply by calling `try_into` on the entire slice and
converting the error.
Enhance Witness struct element access methods:
- Rename `nth()` to `get()` for clearer slice-like element retrieval
- Introduce `get_back()` method for flexible reverse indexing
- Remove redundant `second_to_last()` and `third_to_last()` methods
- Add `#[track_caller]` to index implementation for better error tracking
- Update all references to use new method names
- Improve documentation with usage examples
The changes provide a more intuitive and consistent approach to
accessing witness elements.
The `hex` crate is not always desirable - e.g. when the consumer wants
to work with raw data only. We already had this optional in `hashes` but
if `hashes` is going to depend on `internals` it would break this
property.
This change makes `hash` optional, since it's easy: there's just one
struct that depends on it.
The `{W}PubkeyHash` and `{W}ScriptHash` types are not likely to be used
directly by consumers of the library because we have other function that
return them and are more ergonomic to use. There is therefor no good
reason to re-export them from the crate root.

High priority because it blocks a bunch of work and should be probably swiftly backported.

Align with Bitcoin Core's policy by reducing the minimum non-witness
transaction size from 82 to 65 bytes. This change allows for more
minimal transaction cases (e.g., 1 input with 1 OP_RETURN output),
while still maintaining protection against CVE-2017-12842.

I don't know what I was thinking when I move the taproot hash types to

blockdata in `primitives`.
Move the taproot hash types back to `bitcoin::taproot` and remove the
extension traits.
As part of the 1.0 effort and forward maintainability hide the internals
of the two error types in the `script` module. Add getters to get at the
invalid size.

Bitcoin block headers have a timestamp. Currently we are using a
`u32`. while this functions correctly it gives the compiler no chance
to enforce type safety.
Add a `Timestamp` newtype that is a thin wrapper around a `u32`.
Document it and test the API surface in `api.rs`.
We already have `tapscript` method on `Witness` which is broken because
it doesn't check that the leaf script is a tapscript, however that
behavior might have been intended by some consumers who want to inspect
the script independent of the version. To resolve the confusion, we're
going to add a new method that returns both the leaf script and, to
avoid forgetting version check, also the leaf version.
This doesn't touch the `tapscript` method yet to make backporting of
this commit easier. It's also worth noting that leaf script is often
used together with version. To make passing them around easier it'd be
helpful to use a separate type. Thus this also adds a public POD type
containing the script and the version. In anticipation of if being
usable in different APIs it's also generic over the script type.
Similarly to the `tapscript` method, this also only adds the type and
doesn't change other functions to use it yet. Only the newly added
`taproot_leaf_script` method uses it now.
This is a part of #4073
The previous commit fixed a bug when `taproot_control_block` returned
`Some` on key-spends. This adds a test case for it which succeeds when
applied after the previous commit and fails if applied before it.
The `taproot_control_block` did not properly detect whether it deals
with script spend or key spend. As a result, if key spend with annex was
used it'd return the first element (the signature) as if it was a
control block.
Further, the conditions identifying which kind of spend it was were
repeated multiple times but behaved subtly differently making only
`taproot_control_block` buggy but the other places confusing.
To resolve these issues this change adds a `P2TrSpend` enum that
represents a parsed witness and has a single method doing all the
parsing. The other methods can then be trivially implemented by matching
on that type. This way only one place needs to be verified and the
parsing code is more readable since it uses one big `match` to handle
all possibilities.
The downside of this is a potential perf impact if the parsing code
doesn't get inlined since the common parsing code has to shuffle around
data that the caller is not intersted in. I don't think this will be a
problem but if it will I suppose it will be solvable (e.g. by using
`#[inline(always)]`).
The enum also looks somewhat nice and perhaps downstream consumers could
make use of it. This change does not expose it yet but is written such
that after exposing it the API would be (mostly) idiomatic.

This commit addresses #4041 by making the transaction::Version field private
Changes:
- Make the `Version` field private with `pub(crate)`
- Rename `non_standard` to `maybe_non_standard` for clarity since it accepts both standard and non-standard versions
- Add `#[inline]` attributes to small, frequently used methods:
- `as_u32`
- `maybe_non_standard`
Users now must use either:
- Constants (`Version::ONE/TWO/THREE`) for standard versions
- `maybe_non_standard` method for any version (standard or non-standard)

For private WIF keys corresponding to a compressed address,
the last byte of the key needs to be 0x01, but the API
doesn't enforce this when using PrivateKey::from_wif(). So,
invalid keys can be accepted.
Thus we check if the last byte is equivalent to 0x01
if the key's length is 34 (which indicates it's
compressed).
Currently in order to release `hashes v1.0` we need to 1.0 `io` as well.
For multiple reasons, many out of our control, the `io` crate may not
stabalise any time soon.
Instead we can invert the dependency between the two crates.
This is an ingenious idea, props to Kixunil for coming up with it.
Notes
- `io` does not currently re-export the `hashes` crate.
- This work highlights that we cannot call `hash_reader` on a siphash.
- The `Hmac::hash_reader` uses the default key which may not be obvious.

different types so it is not possible to mix them up.
Add a new `sha256t::HashEngine<T>` where `T` is a tag the same as on
`sha256t::Hash<T>`.
Now we have an associated const we can do away with the `engine` trait
method all together. Users can call `Hash<FooTag>::engine` instead. This
is better because its an API more similar to the other hash types and
therefor easier to discover and remember.

Use the more idiomatic to_fee instead of `fee_wu`. Since the method
takes a strongly typed argument, remove `wu` from the method name
to improve clarity.
We want to get rid of this constant, so we replace it in tests with 0
amount, empty script. Notably, the tests were already using it as a
dummy value - the exact amount was irrelevant, so this change doesn't
break anything.
The `encode_signing_data_to_inner` function previously constructed a
transaction internally, requiring a bunch of allocations, which it'd
then consensus-serialize into a writer (hasher). It also used a dummy
`TxOut::NULL` value which we want to get rid of.
To get rid of both allocations and the NULL value we serialize the
transaction on-the-fly. Because the encoding doesn't involve witnesses
it's not too complicated and the consensus encoding will never change so
there are no desync bugs possible. We may later change this to an
abstract transaction though.

We plan on enforcing MAX_MONEY in the amount types. In preparation use
MAX_MONEY in the serde regression test instead of the arbitrary, and too
large DEADBEEFCAFEBABE value.
We have an `_unchecked` amount constructor that makes no assumptions
about the argument. We would like to start enforcing MAX_MONEY but the
diff to introduce this is massive. In an effort to make it smaller we
can do all the hardcoded ints first. We did this already but a bunch
more snuck in or were missed.
In any amount constructor that passes in a hardcoded const as a decimal
integer (i.e., not hex) use the `_unchecked` version.
Done in preparation for enforcing MAX_MONEY.
New nightly lint warning "called `Iterator::last` on a
`DoubleEndedIterator`; this will needlessly iterate the entire iterator"
Code that gives the warning is correct, allow the lint to remove the
warning.
Update rustc nightly to 2025-01-16
Back in 2022 we elected to use `mutagen` for mutation testing. Since
then `cargo mutants` has progressed to a point where we would now like
to use it instead.
Remove all the `mutagen` stuff and update the lock files.

In #3847 we added an `InvalidCharError` into one of the variants of
`ParsePublicKeyError` but we forgot to update the trait
implementations.
Fix the `error::Error` and `Display` implementations for
`ParsePublicKeyError`. While we are at it match on `*self` as is
typical in this codebase.

Currently `InputString` is in the public API of `units` because of the
trait bound on `parse::int()`. We can just do the monomorphisisation
manually to remove it.
This patch renames `int` to have three different names, one for `&str`
one for `String`, and one for `Box<str>`.

e09bdb5f98 Add BIP324 V2 p2p network message support (Nick Johnson)
Pull request description:
Migrating over the BIP324's library's V2 network message encoding and decoding. As discussed over in https://github.com/rust-bitcoin/rust-bitcoin/discussions/2959, this is probably the natural home for it and also cleans up some gross copy/pasta of some of the encoding/decoding chain logic.
This patch adds `V2NetworkMessage` which wraps a `NetworkMessage`, but handles the V2 encoding and decoding. It is a parallel of the existing `RawNetworkMessage` (which mentioned before, may be better described as `V1NetworkMessage` https://github.com/rust-bitcoin/rust-bitcoin/issues/3157). A priority of this patch was to not re-invent any wheels and try to use the existing patterns as much as possible.

29a71de928 Bound Address parsing on NetworkValidationUnchecked (Tobin C. Harding)
cf455d3a06 Fix typo in prifixes (Tobin C. Harding)
Pull request description:
Currently it is not possible for downstream to use a generic on the `Address` type in structs in conjuncture with
derives (`serde::Deserialize` and `Display`) because our impls are only done for `NetworkUnchecked` (as they should be).
However, as observed by dpc, if we add a secondary marker trait and use it to bound the impls, implementing the new marker for `NetworkUnchecked` then downstream can use derives by way of
```
#[derive(Serialize, Deserialize)]
struct Foo<V>
where V: NetworkValidation,
{
#[serde(bound(deserialize = "V: NetworkValidationUnchecked"))]
address: Address<V>,
}
```
This is cool as hell because the `Address` type is currently a royal PITA.
Patch 1 is trivial cleanup.
To get past a build error in `FromStr` I used this little trick
```rust
// We know that `U` is only ever `NetworkUnchecked` but the compiler does not.
Ok(Address(address.0, PhantomData::<U>))

Pull request description:
We have a `_unchecked` constructor now for both `Amount` and `SignedAmount`. Soon we would like to start enforcing the `MAX_MONEY` invariant in both amount types. To make that change easier do a few refactorings:
- Patch 1 and 2 introduce local variables for amount constructors.
- Patch 3 replaces the local variables introduce in (1) and (2) with macros
- Patch 4 uses `_unchecked` constructor for hard coded integers
The strange patch separation is done intentionally so we don't inadvertently reduce test coverage by using the wrong constructor. I made this mistake already in a previous PR, lesson learned.
Note please, the macro introduced in patch 3 is in preparation for enforcing `MAX_MONEY`. The macros allow us to panic (`from_sat().unwrap()`) instead of using the `_unchecked` version.

72e97c637f Add a hash value to Inventory's Error variant (Nick Johnson)
Pull request description:
I am working on adding BIP324 V2 p2p network message support to the p2p module and ran into a little snag. I can post a draft branch of that work if helpful, but the general strategy is to add a `V2NetworkMessage` which operates in parallel with the existing `RawNetworkMessage` type (which is a bit of misnomer and may be better described in the future as `V1NetworkMessage`, see #3157). This allows both p2p message types to hook into the existing `Encodable`/`Decodeable` chain.
But the `Error` variant of the `Inventory` type message does not have symmetrical encoding and decoding paths. Encoding writes out a zero'd 32 bytes while decoding ignores it completely. And while it is not clear to me if there is [requirement written down](https://en.bitcoin.it/wiki/Protocol_documentation#Inventory_Vectors) anywhere, [bitcoin core does appear to always expect a hash](c1252b14d7/src/protocol.h (L499)) even with the `Error` variant where it is meaningless.
I believe rust-bitcoin's handling of this was never a problem before because the top level `RawNetworkPackage` pulls all the required bytes off a reader before decoding them. But this is not as easy to do with the v2 p2p network messages since the length is decoded at the transport level, not the message itself. I believe it is preferable for the Decoders to *not* assume that all bytes have been pulled off already given their input stream interface. Maybe somewhat surprisingly, this is the only issue I have run into so far adding the v2 encoding and decoding paths. As it is now, the code panics with an `Unconsumed` because it hasn't pulled the dummy zero bytes off the reader.
This patch adds the 32 byte array to the Error variant in order to make its Encoding and Decoding paths symmetrical. This also allows a reader to discard the 32 bytes when decoding a message while cleanly keeping things hooked up with the `Decodeable` chain. The hash is still not exposed to the caller.
This is *a way* to solve my issue, but not sure if it will cause more confusion than its worth. I tried a few other strategies, but preferred this one due to how well it hooks into `Decodeable`.

Any SignedAmount can now be cast to Amount since the range is the same.
Specifically, the range for SignedAmount is (- 21 million, 21 million)
while the range for Amount is (0, 21 million). Therefore any value from
Amount can be cast to a SignedAmount and it will work. Note it's not
the same and still requires checking when going from SignedAmount to
Amount since Amount can't handle the negative range.
As a side effect of changing the return type, TryFrom is no longer valid
and does not compile. Therefore in addition to changing the return
type, TryFrom is also removed.

The Amount type provides better type safety and is more appropriate in
this context than u64. Currently the checked arithmetic operations for
Amount and u64 are identical in behavior. Therefore, this refactor does
not result in any behavior change and is purely cosmetic.
While the hash value of the Error variant is meaningless, the variant
still conforms to all other Inventory messages and requires a 32
byte hash to be sent over the wire. This is how bitcoin core operates.
This patch adds the 32 byte array to the Error variant in order to make
its Encoding and Decoding paths symmetrical. This also allows a reader
to discard the 32 bytes when decoding a message. The hash is still not
exposed to the caller.
This was never a problem before because the top level RawNetworkPackage
pulls all the required bytes off a reader before decoding. But this is
not as easy to do with the v2 p2p network messages.

We need to do a quick release because it turns out I was wrong in
thinking that making `hex` an optional dependency is not a breaking
change.
```
the package `bitcoin` depends on `bitcoin_hashes`, with features: `hex`
but `bitcoin_hashes` does not have these features. It has a required
dependency with that name, but only optional dependencies can be used as
features.
```
Add a changelog, bump the version, depend on the new version repo wide,
and update the lock files - like its our job.

d1dd63d6d4 Remove wildcard in script re-exports (Tobin C. Harding)
Pull request description:
Woops, this should have been done before v0.101.0 was released.
Move the `ScriptHash` and `WScriptHash` types to `primitives`.
Requires moving constants and error types as well. We re-export the errors because they are in the `mod.rs` file so they should appear in both `primitives::script::FooError` and `bitcoin::script::FooError`.
