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`.

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)

In case its useful, the shell function I used to do these changes is:

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.

`SigHash` because 'sighash' is a single word. We should apply the same
logic to functions and variable names.

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.

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.

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)

Iterates all scripts present in TapTree in DFS order returning `(depth, script)` pairs.

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 currently implement `Display` and `FromStr` on `EcdsaSigHashType` and
use them in the `serde_string_impl` macro to implement ser/de.
Mirror this logic in `SchnorrSigHashType`.
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
This macro is no longer needed since we bumped MSRV to 1.29.
We can implement `core::ops::Index` directly since all the inner types
implement `Index` already.
This significatnly refactors the amount formatting code to make
formatting more configurable. The main addition is the
`amount::Display` type which is a builder that can configure
denomination or other things (possibly more in the future).
Further, this makes all representations of numbers minimal by default,
so should be documented as a possibly-breaking change.
Because of the effort to support all other `fmt::Formatter` options this
required practically complete rewrite of `fmt_satoshi_in`. As a
byproduct I took the opportunity of removing one allocation from there.
Closes#709
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.
This function uses neither "Block" nor "Visual" style (as defined by
`rustfmt`). This is unusual, code that is regular is less jarring to
read. We tent to use "Block" style for functions so elect to do that
here.
Our usage of `where` statements is not uniform, nor is it inline with
the typical layout suggested by `rustfmt`.
Make an effort to be more uniform with usage of `where` statements.
However, explicitly do _not_ do every usage since sometimes our usage
favours terseness (all on a single line).
We have a few instances of strange indentation:
- Incorrect number of characters
- Usage of neither "Block" style or "View" style (elect to use "Block")
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.

Update our `rust-secp256k1` dependency to the latest version.
Requires doing:
- Add a new variant to `Error` for the case where parity of the internal
key is an invalid value (not 0 or 1).
- Use non-deprecated const
Changes the API from TweakedPublicKey to XonlyPublicKey. I believe we
introduced TweakedPublicKey to guard against creating address API. This
is confusing because when we want to verify control block we have to
call dangerous_assume_tweak.
This is in true in most cases that the key would be tweaked, but we only
want to guard in while creating a new address. If we want to verify
blocks, we should deal with native X-only-keys regardless of how they
were created

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.

Pull request description:
I believe this avoids some allocation of creating a vec of TxOut to
create a slice incase the data is already available in psbt/other
methods.
See #834

This avoids some allocation of creating a vec of TxOut to
create a slice incase the data is already available in psbt/other
methods. Facilitates creation of Prevouts from &[TxOut] as well as
&[&TxOut]
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.
151173821b Use fn name to_ instead of into_ (Tobin Harding)
Pull request description:
Rust convention is to use `to_` for conversion methods that convert from
an owned type to an owned `Copy` type. `into_` is for owned to owned
non-`Copy` types.
Re-name conversion methods that use `into_` for `Copy` types to use
`to_`, no need to deprecate these ones because they are unreleased.
**Note to maintainers**
This is similar in concept to #798 but only touches new code introduced in this release. Has been labelled 'RC fix' for that reason. Please feel free to remove the label if you disagree.

b138428df7 Re-export public map types from root level (Tobin Harding)
Pull request description:
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.
Found while testing `master` with `rust-miniscript`.
