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
}

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'.

Pull request description:
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.

e27f8ff594 TapTree iterator implementation (Dr Maxim Orlovsky)
Pull request description:
Implemented after @sanket1729 suggestion in https://github.com/rust-bitcoin/rust-bitcoin/issues/895#issuecomment-1074366108
Iterates all scripts present in TapTree in DFS order returning `(depth, script)` pairs.
I propose to have it as an RC fix since this functionality is really lacking and may be required for many wallets working with Taproot PSBT even outside of the scope where I originally needed it (OP_RETURN tweaks for TapTree described in #895)

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.
The exact code formatting we use is not as important as uniformity.
Since we do not use tooling to control the formatting we have to be
vigilant ourselves. Recently I (Tobin) changed the way default type
parameters were formatted (arbitrarily but uniformly). Turns out I
picked the wrong way, there is already a convention as shown in the rust
documentation online (e.g. [1]).
Use 'conventional' spacing for default type parameters. Make the change
across the whole repository, found using
git grep '\<.* = .*\>'
[1] - https://doc.rust-lang.org/book/ch19-03-advanced-traits.html
In this library we specifically do not use rustfmt and tend to favour
terse statements that do not use extra lines unnecessarily. In order to
help new devs understand the style modify code that seems to use an
unnecessary number of lines.
None of these changes should reduce the readability of the code.
Do various whitespace refactorings, of note:
- Use space around equals e.g., 'since = "blah"'
- Put return/break/continue on separate line
Whitespace only, no logic changes.
5e2449922d Separate merge logic out of Map trait (Tobin Harding)
Pull request description:
Recently we (*cough* Tobin) made the `Map` trait private and neglected
to add a public API for merging together two PSBTs. Doing so broke the
`psbt` module.
Add a public trait `Merge` and implement it for
`PartiallySignedTransaction` using the code currently in the `merge`
method of the now private `Map` trait.
Motivated by https://github.com/rust-bitcoin/rust-bitcoin/pull/841

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.
This changes the type of secp signature from secp256k1::Signature to
bitcoin::PublicKey. Psbt allows storing signatures for both compressed
as well as uncompressed keys. This bug was introduced in #591 while
trying to change the type of BIP32 keys from bitcoin::PublicKey to
secp256k1::PublicKey.

b138428df7 Re-export public map types from root level (Tobin Harding)

We currently have the `map` module private but containing a bunch of types that are needed in the public API (specifically in a `PartiallySignedTransaction`).
To give access to them re-export the `util::psbt` module at the root level.
