This creates a few primitive functions for handling iterators and uses
them to avoid repeated code. As a result not only is the code simpler
but also fixes a forgotten bound check. Thanks to a helper function
which always does bounds check correctly this can no longer be
forgotten.
This refactors `blockdata::script::Instructions` to use
`::core::slice::Iter<'a, u8>` instead of `&'a [u8]` to better express
the intention and to avoid some slicing mistakes. Similarly to a
previous change this uses a macro to deduplicate the common logic and
the new `read_uint_iter` internal function to automatically advance the
iterator.

Pull request description:
This PR makes existing taproot script iterator to iterate `LeafScript` values instead of constructed `(u8, &Script)`. First, this is more idiomatic (iterator should not construct value but iterate through real internal representation); second information about merkle path of the scripts is required for me downstream to implement OP_RETURN taproot commitments.
The PR also removes unnecessary iterator type, replacing it with a slice iterator type from the core rust library.
I am asking to include this PR into RC fix scope, since it is required downstream.

In the future, TapTree may iterate over different node types, and that's why it does not have `iter()` function; using instead `script_leafs`. Thus, we should not have IntoIterator implementation as well
Previously used depth and script tuple missed information about the leaf version.
All three comprises already existing type `LeafInfo` which was made public in
previous commits.

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
}

f27c4a541d Added push_x_only_key(..) and its test. (mpls)
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`.
