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)

Pull request description:
The `unknown` key used in the `Psbt` (in `serde_regression_psbt` test) is not really unknown. Also the `preimages` in the `Input` don't seem to be valid. Though they don't affect the tests because of the `serde::serialize`, the `Psbt` itself is invalid and hence this PR.

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`
- `OP_CHECKMULTISIG`
`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.
```
Block 350338, 89 multisig
Block 350340, 29 multisig

026a55809e Fix: Script::count_sigops parsing should not return a Result (junderw)
Pull request description:
When implementing some tests for the Transaction PR, I noticed that there were coinbase transactions that would pass Bitcoin Core parsing and fail my code.
It turns out that the Script parsing for sigops calls `break` to exit the loop and returns the current n value whenever there is an EarlyEndOfScript error.

These docs do not add that much value, we do not typically bother
documenting `From` and `TryFrom` implementations because they are super
well known and its obvious from the function signature what is going on.
The `address::Error` is module level general, we can make the code
easier to maintain and easier to stabalize by splitting the parse error
out of the general error.
Create a `ParseError` that is returned by `FromStr for Address`. Remove
the now unused variants from the general `address::Error`.
In an effort to reduce the number of lines of code import the error
variants locally within the `Display` impl on `Error`.
Refactor only, no logic changes.
Split the error code out of `address/mod.rs` and into
`address/error.rs`. Code move only, no changes other than to
imports/exports etc. to make it build.

This is #1792 but does not use a wildcard and also grabs the other hashes that we recently moved.

53f68383b7 hashes: Bump version to 0.13.0 (Tobin C. Harding)
Pull request description:
In preparation for `hashes` release, bump the version. Depend on new version in `rust-bitcoin`.
Note the `bitcoin-private` addition to the lock files is because we temporarily have two `bitcoin_hashes` dependencies and the secp one (v.0.12.0) depends on `bitcoin-private`.

We currently have a bunch of functions that are infallible if the
`index` argument is within-bounds however we return a `SignError`, this
obfuscates the code.
Add an `IndexOutOfBoundsErorr`. While we are at it make it an enum so
users can differentiate between which vector the out of bounds access
was attempted against.
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.
The `ThirtyTwoByteHash` trait is defined in `secp256k1` and used in
`hashes` as well as `bitcoin`. This means that we must use the same
version of `hashes` in both `bitcoin` and `secp256k1`. This makes doing
release difficult.
Remove usage of `ThirtyTwoByteHash` and use `Message::from_slice`.
Include TODO above each usage because as soon as we release the new
version of secp we can use the new `Message::from_digest`.
This is step backwards as far as type safety goes and it makes the code
more ugly as well because it uses `expect` but thems the breaks.
BIP-32 defines 4 4-byte consts used as version bytes; currently we are
hardcoding the version bytes in multiple places.
Add BIP-32 version bytes consts and use them throughout the module.
The BIP-32 extended public key and extended private key exist in the
Bitcoin vernacular as xpub and xpriv. We can use these terms with no
loss of clarity.
Rename our current BIP-32 types
- `ExtendedPubKey` to `Xpub`
- `ExtendedPrivKey` to `Xpriv`
This patch is a mechanical search-and-replace, followed by running the
formatter, no other manual changes.
4300cf2210 Add p2wpkh and p2wsh signature hash functions (Tobin C. Harding)
Pull request description:
The word "segwit" refers to segwit v0 and taproot but these functions are version specific. Add `v0` into the function names.
This is similar to #1994, both based on recent post of mine to bitcoin dev mailing list.

Pull request description:
Add a base weight const to TxIn. I also used this const in strippedsize() and scaledsize(). As a different PR, I think strippedsize and scaledsize could return Weight instead of usize. Also added a small commit to re-arrange commit messages.

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.
During the 0.30.0 release we removed the re-exports of hash types. This
upset some folk and since the aim of our re-exports is not exactly clean
as well as the fact that the public API surface is not yet fixed just
re-export all the hash types at the crate root again.
This is 1792 but does not use a wildcard and also grabs the other

The word "segwit" refers to segwit v0 and taproot but currently we have
`segwit_signature_hash` that is version specific (segwit v0).
- Rename `segwit_encode_signing_data_to` to
`segwit_v0_encode_signing_data_to`
- Add `p2wpkh_signature_hash` and `p2wsh_signature_hash` functions
We keep the single encode function because the error handling is better
that way.
While we are at it test the bip-143 test vectors against all the
sighash types of wrapped p2wsh.

Currently the `bitcoinconsensus` error is part of the public API. This
hinders maintainability because changes to the verison of
`bitcoinconsensus` force a re-release in `rust-bitcoin`. This is
an unnecessary maintenance burden, we can wrap the error instead.

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.)
