bea5569cd3 Remove duplicate must_use (Tobin C. Harding)
Pull request description:
Clippy emits:
warning: this function has an empty `#[must_use]` attribute, but returns a type already marked as `#[must_use]`
This is because the return type of the function `legacy_encode_signing_data_to` is `EncodeSigningDataResult` which is
already marked as `must_use`. There is no need to have `must_use` on the function also.

Hey apoelstra, this PR is needed before any other PR can get a green CI run. The PR that introduced this warning must have had a green CI run before the 'add clippy to CI' PR merged allowing it to merge without re-running CI.

I'm guessing this got through to master because we only just added
clippy to CI.
Fix#1020 (see more relevant discussion there)
This definitely makes the amount of generics compiler
has to generate by avoding generating the same functions
for `R`, &mut R`, `&mut &mut R` and so on.

(*) - I'm benchmarking on a noisy laptop. Take this with a grain of salt. But I think
at least it doesn't make anything slower.
While doing all this manual labor that will probably generate conflicts,
I took a liberty of changing generic type names and variable names to
`r` and `R` (reader) and `w` and `W` for writer.

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:

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.

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`.

7a3bb7d3ec Replace runtime size check with compile time check (Tobin C. Harding)
Pull request description:
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_asert!` macro.
## Note
This PR is the first patch from a [recently closed PR](https://github.com/rust-bitcoin/rust-bitcoin/pull/953). Props to @elichai for the macro idea in the review of that PR.

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.
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: 221 ns/iter (+/- 102)
The reason why the small witness doesn't get big perf boost is because by default vec allocates 4 slots
