Pull request description:
Our usage of `SigHash` implies that 'sighash' is _two_ words; 'sighash' is a well known word in the Bitcoin ecosystem it should appear in identifiers as `Sighash`.
Change various types, variants, and code comments to use sighash as a single word.
- Patches 1-8 are code changes `s/SigHash/Sighash/g`
- Patch 9 is code changes `s/sig_hash/sighash/g`
- Patch 11 is docs fixes
Fixes: #911
## Note to reviewers
I've been particularly pedantic with the patch separation because we are so close to release.
Done as separate patches to make review easier if review is to be done by reading the diffs. Perhaps at least one person could verify this PR programmatically by doing
- Reset the last 2 patches (those are easy to do manually)
- Check out master
- Do `s/SigHash/Sighash/g` on all source files (bash function below)
- Use `git diff branchA..branchB` to verify
The difference between the two branches should only include comment lines (last three patches) and these seven instances of `SigHash:
```
CHANGELOG.md:82:- [Add FromStr/Display implementation for SigHashType](a4a7035a94)
CHANGELOG.md:93:- [Introduce `SigHashCache` structure](https://github.com/rust-bitcoin/rust-bitcoin/pull/390) to replace `SighashComponents` and support all sighash modes

```
In case its useful, the shell function I used to do these changes is:
```bash
function search-and-replace() {
if (($# != 2))
then
echo "Usage: $0 <this> <that>"
return
fi
local this="$1"
local that="$2"
# For all files containing $this, replace $this with $that.
for file in $(git grep -l "$this")
do
perl -pi -e "s/$this/$that/g" "$file"
done
}

Pull request description:
**Issue**
I can not use [`XOnlyPublicKey`](ae985dd191/src/key.rs (L973)) in my Scripts which prevents me from working with Taproot.
**Cause**
The current version of [`script::Builder`](0a2d45de09/src/blockdata/script.rs (L121)) does not accept `XOnlyPublicKey`s.
**Solution**
So, I created a function `push_xkey(self, key: &XOnlyPublicKey)` based on the existing [`push_key`](0a2d45de09/src/blockdata/script.rs (L914)) function. I also augmented an [existing test](0a2d45de09/src/blockdata/script.rs (L1108)) in an attempt to reach testing parity with existing code.
After toying around with `push_xkey`, it seems to work on my end.

e3f173e521 Require taproot tree depth argument always to be u8 (Dr Maxim Orlovsky)
Pull request description:
There is an inconsistency in depth type: some places uses `u8` (which is reasonable, since the depth can't be >127), others use `usize`. This PR makes API consistent.
I think this should be a RC fix, since it affects newly introduced API in this release and it will be bad to make a breaking changes the next version after its introduction.

Recently we added a bunch of additional sighash types, some of the code
comments became stale. Use the non-specific term 'sighash type' instead
of a particular sighash identifier in comments to make the comments more
applicable.
Recently we update all types and docs to use `Sighash` instead of
`SigHash` because 'sighash' is a single word. We should apply the same
logic to functions and variable names.
Do not use an underscore in the identifier 'sighash'.
Our usage of `SigHash` implies that 'sighash' is _two_ words; 'sighash'
is a well known word in the Bitcoin ecosystem it should appear in
identifiers as `Sighash`.
Rename the `SigHash` type to `Sighash`.

c25eddd187 Remove unnecessary documentation (Tobin Harding)
8631474f08 Improve docs in taproot module (Tobin Harding)
Pull request description:
I should have done this PR a month ago, my bad. This one is kind of important IMO because we are going to have so many people looking at this part of the code soon as we release.
As has been done in other places in the codebase; improve the docs in the `taproot` module by doing:
- Use full sentences (capital letters + full stops)
- Use back ticks and links for types where appropriate
- Fix grammar
- Fix stale docs
- Use third person for describing functions
- Use 100 character line width
- Use markdown sections (`# Examples`, `# Returns`) where appropriate
- Separate brief heading from extended description when appropriate
- Use `///` for all functions/types (both private and public)
I also did:
- Build the docs and check all the links
- Read all the built docs, check for sanity and pretty-ness
Its all in one patch, I couldn't really tease it apart. I can try a bit harder if it proves too annoying to review.

The newly introduced `PsbtSigHashType` uses very different serde formatting from previously used `EcdsaSigHashType`; for instance it does not output human-readable sighash. This is especially obvious when printing out PSBT as JSON/YAML object and is a breaking change from the `0.27`. Serde human-readable implementation requires `Display/FromStr`, which were also absent.

51fef76129 feat: Add Address.is_related_to_pubkey() (Andrew Ahlers)
Pull request description:
## Motivation
This is addressing the second half of this comment: https://github.com/rust-bitcoin/rust-bitcoin/pull/684#issuecomment-1012136845
> but would accept a PR (or two PRs) that returns Result<bool, UnsupportedAddress> and a method to check if a PublicKey is associated with an address.
(The first half was addressed [here](https://github.com/rust-bitcoin/rust-bitcoin/pull/819))
These changes will help build out and improve message signature verification. We don't necessarily need to add it to this crate but it allows for easy verification with something such as:
1. recovering a pubkey
2. checking if that pubkey relates to the given address
## Possible Improvements
- There is likely a better name than `is_related_to_secp256k1_key()`
- This could drop the `secp256k1` part of the name and take in a Pubkey enum that also supports Schnorr pubkeys and then this could be used for taproot addresses as well. This felt like a much larger change that will likely get turned down. Verifying taproot is simple enough and if absolutely desired, similar functions can be added for schnorr keys (tweaked and untweaked)

It is possible, although not immediately obvious, that it is possible to
create a `PsbtSigHashType` with a non-standard value.
Add a unit test to show this and also catch any regressions if we
accidental change this logic.
Improve the `PsbtSigHashType` conversion methods by doing:
- Re-name `inner` -> `to_u32` as per Rust convention
- Add `from_u32` method
Note, we explicitly do _not_ use suffix 'consensus' because these
conversion methods make no guarantees about the validity of the
underlying `u32`.
The functions `from_u32_standard` and `from_u32_consensus` smell a bit
like hungarian notation. We can look at the method definition to see
that the methods accept `u32` arguments without mentioning that in the
method names.
Remove `_u32_` from the method names. This brings the `from_*` methods
in line with the `to_standard` method also.
Rust naming conventions stipulate that conversion methods from owned ->
owned for `Copy` types use the naming convention `to_`.
This change makes the function name objectively better, however it makes
no claims of being the 'best' name. We have had much discussion on using
`to_standard` vs `to_u32` but are unable to reach consensus.
We have conversion functions that include suffixes `_consensus`
and `_standard` to make it explicit what guarantees are provided by the
returned `u32` value. The `From` implementation reduces the clarity of
the API.
