Currently unmergable because of MSRV but I heard talk about bumping it, so once it's bumped, this is a very much needed change :)

It is more typical in this repo to use `module::Error` instead of a type
alias when importing.
Use `hex::Error` directly instead of `use hex::Error as HexError`.
d882b68a2c Add Script conversion method p2wpkh_script_code (Tobin Harding)
Pull request description:
In order to sign a utxo that does a p2wpkh spend we need to create the
script that can be used to create a sighash. In the libbitcoin docs this
is referred to as the 'script code' [0] (also described in BIP143)
The script is the same as a p2pkh script but the pubkey_hash is found in
the scriptPubkey.
Add a `Script` conversion method that checks if `self` is a v0 p2wpkh
script and if so extracts the pubkey_hash and returns the required
script.
Includes a link to BIP143

f92854a805 Add PSBT alias (Tobin Harding)
Pull request description:
Programmers are inherently lazy and for good reason. I'm yet to see
anyone write `PartiallySignedTransaction` in code that uses
`rust-bitcoin`, its too obvious to add a type alias for PSBTs, let's
just do it ourselves to save everyone else having to do so.
Add public type alias `Psbt` for `PartiallySignedTransaction`.

548725c5fb test: reject message (de)serialization (0xb10c)
fc572aba86 fix: use var_str in 'reject' msgs (0xb10c)
Pull request description:
[BIP-61 defines `response-to-msg`][bip61] (`Reject::message` in rust-bitcoin; the message that triggered the reject) to be a `var_str`. However, by using the `CommandString` it was (de)serialized as 12 byte string. A test is added that de- and serializes two reject messages received from an older Bitcoin Core peer.
Reject message sending has been removed from Bitcoin Core, I'm still receiving them from older peers from time to time.

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.

This adds tests for the previously untested reject message
(de)serialization. The two reject messages were received from an
older Bitcoin Core peer that still sends reject messages.

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
CHANGELOG.md:121: - `SigHash`
src/blockdata/transaction.rs:1190: "SigHash_None",
src/blockdata/transaction.rs:1191: "SigHash_NONE",
src/util/sighash.rs:1175: "SigHash_None",
src/util/sighash.rs:1176: "SigHash_NONE",
```
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.
