24f0441d54 Add PublicKey::to_sort_key method for use with sorting by key (junderw)
Pull request description:
Replaces #524
See previous PR for reasoning.
This solution is a little more straightforward. The name and documentation should be enough to prevent misuse.
We can also impl a to_sort_key for any CompressedKey added later. (or just impl Ord in a BIP67 compliant way)
TODO:
- [x] Add more sorting test vectors. Ideas of edge cases to test are welcome.

19ba7ecc03 Add custom error for unknown address type parsing (Arturo Marquez)
Pull request description:
Adds a custom error `UnknownAddressType(_)` which is returned in cases where an unknown address type tries to be parsed via
`FromStr`. This provides more context for the error, since it contains the `String` that tried to be parsed.

91ff2f628c Introduce SPDX license identifiers (Tobin C. Harding)
Pull request description:
When `rust-bitcoin` was started in 2014 the SPDX license list and short identifiers where not a thing. Now that we have short identifiers and they are gaining popularity in other projects we can consider using them.
- Add links to the SPDX website in the readme
- Shorten the author section to a single line
- Remove all the licence information in each file and replace it with an
SPDX ID (see https://spdx.dev/ids/#how)
Of note:
- If the author of a file is explicitly listed, maintain this information
- If the 'author' is listed as the generic 'Rust Bitcoin developers' just remove the attribution, this is implicit. This does loose the date info but that can be seen at any time from the git index using
`git log --follow --format=%ad --date default <FILE> | tail -1`
apoelstra, please confirm that I'm not treading on your toes here, especially, are you ok with the new 'written by' string format?

4d2291930b Use fragment-specifier literal (Tobin C. Harding)
Pull request description:
Currently we are using the fragment-specifier `expr` in a bunch of
macros for captures that are only used for literals. If we use `literal`
instead it allows the compiler to give slightly more specific error
messages.
The benefits of this change are minor. Of note, this patch found one
unusual macro call site (removed unnecessary `&`).
The macros changed are all internal macros, this is not a breaking change.

We allocated a new vector when serializing a `Witness`. That was
inefficient and unnecessary. Use `serialize_seq` to feed the witness
elements directly into the serializer.
Optimize `Witness` serialization by removing the allocation.

We are almost ready to enable clippy on CI!
First clear a few remaining warnings from feature gated code. Then add a CI job to run clippy using `--all-features` (note no `--all-targets`). Next add githooks directory (this is the patch from https://github.com/rust-bitcoin/rust-bitcoin/pull/1044/commits). Finally add `cargo clippy` to the pre-commit hook.
EDIT: I just realized the running of clippy could have been done in `test.sh` instead of as a github action. Does that matter?

Add a `githooks` directory. Copy the sample pre-commit hook into it.
Add a section to the README explaining how to take advantage of the
githooks.
The sample pre-commit hook includes checks for trailing whitespace that
we are seeing occasionally in PRs.
Done in preparation for adding a clippy githook.
Add a clippy configuration file configuring the MSRV. Add a github
actions job to run clippy on CI.
Please note the job does _not_ use `--all-targets` because doing so
causes:
```
error[E0554]: `#![feature]` may not be used on the stable release channel
--> src/lib.rs:46:54

clippy emits:
warning: this expression creates a reference which is immediately
dereferenced by the compiler
As suggested, remove the explicit reference.
clippy emits a bunch of:
warning: digits grouped inconsistently by underscores
We have a custom grouping elsewhere in this file
10_000_000_00 sats == 10 BTC
Fix up all instances of large sats amount to uniformly using this format
and add compiler directives where needed to shoosh clippy.
clippy emits:
warning: this `else { if .. }` block can be collapsed
In this instance the code is more readable how it is, we should ignore
clippy.
Add compiler directive to quieten warning.
281af7c1b9 Move broken-intra-doc-link lint config to command line (Tobin C. Harding)
Pull request description:
The docs lint `broken-intra-doc-links` has been changed but the new name
is not available in our MSRV, this means we get a build warning. We only
build docs with the nightly toolchain so we can move this lint control
to the docs build command in `test.sh` instead of doing it crate wide.
With this patch applied devs risk not noticing docs link issues until
they hit them on CI _if_ they do not build with the test script or
explicitly pass in `-- -D rustdoc::broken-intra-doc-links`, which no one
is going to do. Hence we add a line to the readme with a shell alias
that can be used to check docs, taken directly from `test.sh`.
