Currently we are unable to build with all features enabled with a
non-nightly toolchain, this is because of the use of
`#![cfg_attr(all(test, feature = "unstable"), feature(test))]`
which causes the following error when building:
error[E0554]: `#![feature]` may not be used on the stable release
channel
The "unstable" feature is used to guard bench mark modules, this is
widely suggested online but there is a better way.
When running the bench marks use the following incantation:
`RUSTFLAGS='--cfg=bench' cargo bench`
This creates a configuration conditional "bench" that can be used to
guard the bench mark modules.

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.

Previous implementations of Witness (and Vec<Vec<u8>>) serde serialization
didn't support human-readable representations. This resulted in long unreadable
JSON/YAML byte arrays, which were especially ugly when pretty-printed (a line
per each byte).
Co-authored-by: Tobin C. Harding <me@tobin.cc>
This also removes tests for JSON backward-compatible encoding. Human-readable
encoding will be changed in the next commit and this will break backward
compatibility, thus that part of the test is removed.

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?

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.

This is because the return type of the function

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.
Add a macro `const_assert` that uses some const declaration trickery to
trigger a compile time error if a boolean expression is false.
Replace runtime checks using `debug_assert_eq!` with the newly defined
`const_assert!` macro.
ec8dadaf86 Implement iter::size_hint and ExactSizeIterator for Witness Iter (Riccardo Casatta)
Pull request description:
close https://github.com/rust-bitcoin/rust-bitcoin/issues/1050
I don't think we need to change the `collect` since it use the `size_hint()` lower bound to initially allocate
// with size_hint
// test blockdata::witness::benches::bench_big_witness_to_vec ... bench: 313 ns/iter (+/- 13)
// test blockdata::witness::benches::bench_witness_to_vec ... bench: 204 ns/iter (+/- 11)
// without
// test blockdata::witness::benches::bench_big_witness_to_vec ... bench: 489 ns/iter (+/- 28)
// test blockdata::witness::benches::bench_witness_to_vec ... bench: 221 ns/iter (+/- 102)
The reason why the small witness doesn't get big perf boost is because by default vec allocates 4 slots

The `ParseAmountError` does not implement `std::error::Error`, must have
been missed when we did the rest.
Implement `std::error::Error` for `ParseAmount`.
Modify from_script functions to return result instead of option so that, in case of errors, there is more
information on what went wrong.

Remove calls to `clone` from types that implement `Copy`.
Clippy warns about creating a reference that is immediately
de-referenced.
Remove unnecessary explicit `&`, while we are at it remove unnecessary
explicit types that appear on the same lines of code.
We only simulate a single connection in the test function `serve_tcp`.
Remove the unused loop (includes an unconditional break after first
iteration) and use `next` directly.

I hope putting it on the most notorious type where people actually notice it is enough. I couldn't find a good way to put it on all other `sha256d` automatically, and copy pasting it seems not worth it.

Pull request description:
Add non_exhaustive compiler directive to AddressType
Currently adding variants to enums is a breaking change. In an effort to
reduce the upgrade burden on users we can use the `non_exhaustive`
compiler directive so that adding a new variant does not cause
downstream code to break.
Add `non_exhaustive` to the `AddressType` since it may be extended in
the future.

Pull request description:
As part of the ongoing error improvement work and as a direct result of [this comment](https://github.com/rust-bitcoin/rust-bitcoin/pull/987#issuecomment-1135563287) improve the `Display` implementations of all our error types so as to not repeat the source error when printing.
The first 5 patches are trivial clean ups around the errors. Patch 6 is the real work.
EDIT: ~CC @Kixunil, have I got the right idea here bro?~ Patch 6 now includes a macro as suggested.

2e7effc604 Feature `use-serde` renamed to `serde` (Martin Habovstiak)
Pull request description:
Features activating external crates are supposed to have same name as
those crates. However we depend on same feature in other crates so we
need a separate feature. After MSRV bump it is possible to rename the
crates and features so we can now fix this inconsistency.
Sadly, derive can't see that the crate was renamed so all derives must
be told to use the other one.

cd8f511fcb blockdata: constants: Use wildcard import in unit tests (Tobin Harding)
71bf19621a Use fully qualified path in macro (Tobin Harding)
Pull request description:
The Lightning network defines a type called 'chain hash' that is used to uniquely represent the various Bitcoin networks as a 32 byte hash value. Chain hash is now being used by the DLC folks, as such it is useful to have it implemented in rust-bitcoin.
One method of calculating a chain hash is by hashing the genesis block for the respective network.
Add a `ChainHash` type that can be used to get the unique identifier of each of the 4 Bitcoin networks we support. Add a method that calculates the chain hash for a network using the double sha256 of the genesis block. Do so using hard coded consts and add unit tests (regression/sanity) that show these hard coded byte arrays match the hash of the data we return for the genesis block for the respective network.
The chain hash for the main Bitcoin network can be verified from LN docs (BOLT 0), add a link to this document.
