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.
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.
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
hashes that we recently moved.
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.

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`

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.
Only commit in the docs and error messages to what we _really_ know.
In an attempt to reduce the likelyhood of the code going stale only
commit to what is guaranteed - that we have an error from a module.
This does arguably reduce the amount of context around the error.
