Pull request description:
Improve the public exports in two ways:
1. Inline re-exports into the docs of the module that re-exports them.
2. Separate public and private use statements
Recently we discussed a way to separate the public and private import statements to make the code more clear and prevent `rustfmt` joining them all together.
Separate public exports using a code block and `#[rustfmt::skip]`. Has the nice advantage of reducing the number of `#[doc(inline)]` attributes also.
1. Modules first, as they are part of the project's structure.
2. Private imports
3. Public re-exports (using `rustfmt::skip` to prevent merge)

On our way to v1.0.0 we are defining a standard for our error types,
this includes:
- Uses the following derives (unless not possible, usually because of `io::Error`)
`#[derive(Debug, Clone, PartialEq, Eq)]`
- Has `non_exhaustive` unless we really know we can commit to not adding
anything.
Furthermore, we are trying to make the codebase easy to read. Error code
is write-once-read-many (well it should be) so if we make all the error
code super uniform the users can flick to an error and quickly see what
it includes. In an effort to achieve this I have made up a style and
over recent times have change much of the error code to that new style,
this PR audits _all_ error types in the code base and enforces the
style, specifically:
- Is layed out: definition, [impl block], Display impl, error::Error impl, From impls
- `error::Error` impl matches on enum even if it returns `None` for all variants
- Display/Error impls import enum variants locally
- match uses *self and `ref e`
- error::Error variants that return `Some` come first, `None` after
Re: non_exhaustive
To make dev and review easier I have added `non_exhaustive` to _every_
error type. We can then remove it error by error as we see fit. This is
because it takes a bit of thinking to do and review where as this patch
should not take much brain power to review.
In a further effort to make the code brain-dead easy to read; use an
explicit implementation of `std::error::Error` that returns `None`
instead of relying on the default trait implementation.
We would like the codebase to be optimized for readability not ease of
development, as such code that is write-once-read-many should not use
macros.
Currently we use the `impl_std_error` macro to implement
`std::error::Error` for struct error types. This makes the code harder
to read at a glance because one has to think what the macro does.
Remove the `impl_std_error` macro and write the code explicitly.
dac627cc09 Feature: Psbt fee checks (junderw)
Pull request description:
Closes#2061
These new methods on Psbt will add checks for high fees by default. The threshold for "high fees" is currently set to 25000 sat/vbyte, which is about 20x higher than the highest next block fees seen on the "Mempool" website.
The primary goal of this change is to prevent users of the library from accidentally sending absurd amounts of fees.
(ie. Recently in September 2023 there was a transaction that sent an absurd amount of fees and made news in the Bitcoin world. Luckily the mining pool gave it back, but some might not be so lucky.)
There are variants of the method that allow for users to set their own "absurd" threshold using a `FeeRate` value. And there is a method that performs no checks, and the method name is alarming enough to draw attention in a review, so at least developers will be aware of the concept.

```
Recently we introduced a bug in the weight/size code, while

were in a total mess because:
- The docs were stale
- The concept of weight (weight units) and size (bytes) were mixed up
I audited all the API functions, read some bips (141, 144) and re-wrote
the API with the following goals:
- Use terminology from the bips
- Use abstractions that mirror the bips where possible

Please note, this PR introduces panics if a sciptPubkey overflows the calculation `weight = spk.size() * 4`.

Pull request description:
In order to create the witness to spend p2wpkh output one must create a `Witness` that includes the signature and the pubkey, we should have a function for this.
## Notes
The PR originally added a `push_p2wphk` method, this is now instead a constrcutor `Witness:p2wpkh` (after review discussion below).
- Patch 1 changes `push_bitcoin_signature` to take an `ecdsa::Sigtnture` instead of an `ecdsa::SerializedSignature`
- Patch 2 takes a `secp256k1::PublicKey` removing the need for an error path (discussed below).

The `Witness::push_bitcoin_signature` method is old and a bit stale.
Bitcoin has taproot signatures now so the name is stale, also we have
the `crate::ecdsa::Signature` type that holds the secp sig and the hash
type so we can use that instead of having two separate parameters.
Add a new, up to date, `Witness::push_ecdsa_signature` function and
deprecate the `push_bitcoin_signature` one.
There is no logical default for the transaction version number, there is
only pre-bip68 (v1) and post-bip68 (v2). Uses should specify the version
they want not rely on us making the choice.
(I originally added this impl to support testing, this was in hindsight
the wrong thing to do, props to Sanket for noticing.)
One of our stated aims is to make it possible to learn bitcoin by using
our library. To help with this aim add to private consts for the segwit
transaction marker and flag serialization fields.
158ba26a8a Feature: Count sigops for Transaction (junderw)
Pull request description:
I copied over the sigop counting logic from Bitcoin Core, but I made a few adjustments.
1. I removed 2 consensus flags that checked for P2SH and SegWit activation. This code assumes both are activated. If we were to include that, what would be a good way to go about it? (ie. If I run this method on a transaction from the 1000th block and it just so happened to have a P2SH-like input, Bitcoin Core wouldn't accidentally count those sigops because the consensus flag will stop them from running the P2SH logic. Same goes for SegWit)
3. Since there's no guarantee that we have an index from which we can get the prevout scripts, I made it into a generic closure that looks up the prevout script for us. If the caller doesn't provide it, We can only count sigops directly in the scriptSig and scriptPubkey (no P2SH or SegWit).
## TODO
- [x] Write tests for transaction sigop counting
~~Edit: The test changes are just to get the 1.48 tests passing. I'll remove them and replace them with whatever solution that is agreed upon in another PR etc.~~
Edit 2: This is the code I used as a guide:
8105bce5b3/src/consensus/tx_verify.cpp (L147-L166)
Edit 3: I found a subtle bug in the implementation of `count_sigops` (https://github.com/rust-bitcoin/rust-bitcoin/pull/2073#issuecomment-1722403687)

BIP-68 activated a fair while ago (circa 2019) and since then only
transaction versions 1 and 2 have been considered standard.
Currently in our `Transaction` struct we use an `i32`, this means users
can construct a non-standard transaction if they do not first look up
what the value should be. We can help folk out here by abstracting over
the version number.
Since the version number only governs standardness elect to make the
inner `i32` public (ie., not an invariant). The aim of the type is to
make life easy not restrict what versions are used.
Add transaction::Version data type that simply provides two consts `ONE`
and `TWO`.
Add a `Default` impl on `Version` that returns `Version::TWO`.
In tests that used version 0, instead use `Version::default` because the
test obviously does not care.

acbf23aaa5 Add `is_multisig` helper to Script type (Clark Moody)
Pull request description:
A new `is_multisig` helper method to classify bare multisig output scripts.
The form of a valid multisig script is:
- Pushnum `M`
- <N> pubkeys
- Pushnum `N`

`N` must equal the number of pushed pubkeys, and `M` must be less than or equal to `N`.
I've tested this against the RPC output of Core at the block level, checking that the total number of multisig outputs matches.

Throughout the codebase we cast values to `u64` when constructing a
`VarInt`. We can make the code marginally cleaner by adding `From<T>`
impls for all unsigned integer types less than or equal to 64 bits.
Also allows us to (possibly unnecessarily) comment the cast in a single
place.
Currently if the witness has zero elements or any of the individual
witnesses is empty we panic. Panic is caused by subtracting 1 from a
zero length.
Check the length is non-zero before subtracting 1, print `[]` if empty.
2e3006a729 Add max standard tx weight constant to transaction (yancy)
Pull request description:
Add a constant for the max transaction weight. Similar to [max block weight](1b009b809b/bitcoin/src/blockdata/weight.rs (L35)). This value is pulled from core [here](44b05bf3fe/src/policy/policy.h (L27))

9eff2f2f5e fee_rate: Add public absolute weight convenience functions (Tobin C. Harding)
f00e93bdcd Fix typos in rustdoc (Tobin C. Harding)
f3412325ea weight: Make docs uniform and terse (Tobin C. Harding)
Pull request description:
- Patch 1 is docs cleanup
- Patch 2 adds two functions to `FeeRate`
From the commit log of patch 2:
Calculating the absolute fee from a fee rate can currently be achieved
by creating a `Weight` object and using
`FeeRate::checked_mul_by_weight`. This is kind of hard to discover, we
can add two public convenience functions that make discovery of the
functionality easier.
Add two functions for calculating the absolute fee by multiplying by
weight units (`Weight`) and virtual bytes (by first converting to weight
units).
This seems like an obvious thing so I'm inclined to think that Kixunil left it out for a reason. (Mentioning you here Kix so even if this merges you'll see it in notifications later on.)

Pull request description:
EDIT: The commit hashes below are stale but the text is valid still.
In an effort to "perfect" our error handling, overhaul the error handling in the `crypto` module.
The aim is to do a small chunk so we can bikeshed on it then I can apply the learnings to the rest of the codebase.
Its all pretty trivial except:
- commit `4c180277 Put NonStandardSighashTypeError inside ecdsa::Error variant`
- comimt `5a196535 Add InvalidSighashTypeError`
- commit `05772ade Use defensive documentation`
Particularly the last one might be incorrect/controversial.
Also, please take the time to check the overall state of error code in the `crypto` module on this branch in case there is anything else we want to do.
Thanks

Improve the script hash types by doing:
- Define the types in the `crypto::script` module
- Put the From impls directly below the type definitions
Keep the current crate level re-export so this does not impact the
public API _if_ people are using the re-export but is still a breaking
change.
Improve the pubkey hash types by doing:
- Define the types in the `crypto::key` module
- Add From<&PublicKey> impl for `PubkeyHash`

public API _if_ people are using the re-export but is still a breaking

The `network` module deals with data types and logic related to
internetworking bitcoind nodes, this is commonly referred to as the p2p
layer.
Rename the `network` module to `p2p` and fix all the paths.

As part of an ongoing effort to make our error types stable and useful
add a stand set of derives to all error types in the library.
`#[derive(Debug, Clone, PartialEq, Eq)]`
Add `Copy` if possible and the error type does not include
`#[non_exhaustive]`.
If an error type includes `io::Error` it only gets `#[derive(Debug)]`.

Pull request description:
Use the newly released `hex-conservative` crate, by doing the following:
- Depend on `hex-conservative` in `bitcoin` and `hashes`
- Re-export `hex-conservative` as `hex` from both crate roots.
- Remove all the old hex code from `hashes`
- Remove all the old hex code from `internals`
- Remove the now unused `internals::prelude`
- Fix all the import statements (makes up the bulk of the lines changes in this patch)

This type was defined in the `transaction` module because it was
originally used in a function that had been deprecated in favour of
moving the logic to the `sighash` module.
We just removed the deprecated code so we can now move this type to the
`sighash` module where it is used.
We only keep deprecated code around for one release so we can now remove
code deprecated in v0.30.0
Done in preparation as we gear up for v0.31.0 release.
