When signing a transaction will result in the sighash single bug being
exploitable we should return the 'one array' (equivalent to 1 as a
uint256) as the signature hash.
Add a unit test to verify we return uint256 1 value when use of
SIGHASH_SINGLE is invalid.
When signing a transaction will result in the sighash single bug being
exploitable we should return the 1 array (equivalent to 1 as a uint256)

Currently we are using the correct array value but are re-hashing it,
instead we should directly return it.
7554d76dfe Make Script::witness_version public (Dr Maxim Orlovsky)
Pull request description:
Originally this function was public (at least I was using it in downstream dependency in https://github.com/LNP-BP/descriptor-wallet). Now, in RC1, it became private. It is quite useful to detect witness scriptPubkeys.

## Note to reviewers
Sorry to be a bore and request review on all these docs fixes, this one is all in a single patch which makes it a bit harder to review. It is very similar in content to all the others that are open right now so I'm going to be a bit rude and leave it like this.

Nothing too controversial here :)
The line of code `let mut have_witness = self.input.is_empty();` is
puzzling if one does not know _why_ we serialize in BIP141 style when
there are no inputs.
Add a code comment to save devs spending time trying to work out _why_
this is correct.
The two methods `encode_signing_data_to` and `signature_hash` use the
same docs (one is a public helper for the other). The docs have gotten a
bit stale (refer to deprecated types).
Instead of duplicating all the text, add a statement pointing readers
from the docs of `signature_hash` to the docs on
`encode_signing_data_to`.
Improve the rustdocs for the `blockdata::block` module:
- Use full sentences (capitalisation and full stop)
- Use third person tense instead of imperative
- Improve wording if needed
Currently function contains nested `if` clauses that arguably obfuscate
the code. We can make the code easier to read by pulling out the error
paths and returning them higher up in the function.
Refactor only, no logic changes.
7638d59fa6 Improve rusntdocs for *_hash_ty methods (Tobin Harding)
Pull request description:
Recently we added two new methods with rustdocs. The rustdocs have a few minor things that can be improved.
- Use 'Returns' section for both success and error path returns
- Use markdown heading for section
- [Subjectively] improve wording of docs
@rish-singhal this PR is minor rustdocs stuff that I have recently been learning myself. I hope this makes your future patches easier to do in regards to the docs. FTR there are `# Returns` sections and `# Examples` sections that one can use, no set rules as far as I can tell. I chose `# Returns` in this case because it seemed to work. Please feel free to NACK the wording changes if you do not agree.

Recently we (*cough* Tobin) made the `Map` trait private and neglected
to add a public API for combining together two PSBTs. Doing so broke the
`psbt` module.
Pull the merge logic out of the `Map` trait and put it in methods on
each individual type (`Input`, `Output`, `PartiallySignedTransaction`).
Doing so allows for simplification of return types since combining
inputs/outputs never errors.
Use the term 'combine' instead of 'merge' since that is the term used in
BIP 174.
006193f5b6 feat: Support running CI locally with `act` (Andrew Ahlers)
Pull request description:
Disable problematic jobs that involve Github Actions caching or `cross` whenever the environment is set to ACT. This allows running the CI pipeline locally and hopefully speeds up PR cycle times by reducing unexpected CI pipeline results.
## Motivation
The CI pipeline does not run until maintainer approval. This allows an easy path for contributors to test out the CI pipeline locally and avoid unexpected results. I personally kept hitting issues here due to MSRV always throwing me off
## Potential issues
- `act` does not support Github Actions caching feature which is used in the `fuzz` workflow so I simply disabled it if `act` is detected.
- the `cross` workflow is similarly disabled. I kept hitting `sh: 1: cargo: not found` (see: https://github.com/cross-rs/cross/issues/260). I tried a few different workaround but had no success.
I'm hoping this is acceptable as it still improves the local testing situation and covers the `Tests` workflow
