d9533523ac Remove usage of ThirtyTwoByteHash (Tobin C. Harding)
Pull request description:
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.
For context see #1985

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.

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.

f2c5f19557 Introduce the `small-hash` feature for `bitcoin_hashes` (Alekos Filini)
Pull request description:
When enabled this feature swaps the hash implementation of sha512, sha256 and ripemd160 for a smaller (but also slower) one.
On embedded processors (Cortex-M4) it can lead to up to a 52% size reduction, from around 37KiB for just the `process_block` methods of the three hash functions to 17.8KiB.
The following numbers were collected on `aarch64-unknown-linux-gnu` with `cargo 1.72.0-nightly`.

## Conclusion
On `aarch64` there's overall a ~30% improvement in size, although ripemd160 doesn't really shrink that much (and its performance also aren't impacted much with only a 6% slowdown). sha512 and sha256 instead are almost 40% slower with `small-hash` enabled.
I don't have performance numbers for other architectures, but in terms of size there was an even larger improvements on `thumbv7em-none-eabihf`, with a 52% size reduction overall:

```
I'm assuming this is because on more limited architectures the compiler needs to use more instructions to move data in and out of registers (especially for sha512 which ideally would benefit from 64-bit registers), so reusing the code by moving it into functions saves a lot of those instructions.
Also note that the `const_hash` method on `sha256` causes the compiler to emit two independent implementations. I haven't looked into the code yet, maybe there's a way to merge them so that the non-const `process_block` calls into the const fn.

When enabled this feature swaps the hash implementation of sha512,
sha256 and ripemd160 for a smaller (but also slower) one.
On embedded processors (Cortex-M4) it can lead to up to a 52% size
reduction, from around 37KiB for just the `process_block` methods of the
three hash functions to 17.8KiB.
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.

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.)

27b3c1e0e6 Improve the ScriptHash and WScriptHash types (Tobin C. Harding)
2197f1377f Improve PubkeyHash and WPubkeyHash (Tobin C. Harding)
Pull request description:
Total re-write since review. Now this PR moves the hash type definitions out of `hash_types`. Please see https://github.com/rust-bitcoin/rust-bitcoin/issues/1909#issuecomment-1603634440 for more.
No longer adds unit tests.
Fix: #1909

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.

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`
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.
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 PR has grown.
- Rename the `network` module to `p2p` (fix: #1855)
- add `BorrowMut` to prelude
- Move the `Network`, `ChainHash`, and `Magic` structs to a newly create `p2p::network` module
- Do a few cleanups

55be538dac policy: Add refactor carve out (Tobin C. Harding)
Pull request description:
I have managed to burn out or bore our reviewers/maintainers. Getting two acks is becoming increasingly difficult. I've pestered everyone to the limit that I feel socially comfortable doing so, and as such, am requesting a carve out to the 2-ACK before merge rule.
The primary justification is that I feel we should have a bit more of BDFL and a bit less total consensus if we are to push forwards.

The `ServiceFlags` type is used by the p2p layer. It can live in the
`mod.rs` file of the `p2p` module. Done in preparation for removing the
`p2p::constants` module.
This is a straight code move, the `ServiceFlags` replaces the
current re-export.
The `PROTOCOL_VERSION` const is a p2p layer constant. It can live in the
`mod.rs` file of the `p2p` module.
This is a straight code move, the `PROTOCOL_VERSION` replaces the
current re-export.
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.
