We only check clippy in CI with --all-features, which usually is the
best way to get maximum coverage. But if you try a couple other feature
combos, especially those related to nostd, you can hit more code.

bitcoin: Bump version to 0.32.0-rc1
In preparation for dropping the first release candidate bump the version
and add a changelog.

Please not I went to much more effort that usual with the changelog,
open to review on the overall form - not promising I'll change it but
definitely would like to keep iterating and improving.

If this changelog is appreciated then FWIW I don't think we should
bother automating it, a machine does not have all the context required
to create it.

ffd5664c08 Do not panic if input_index is out of bounds (Tobin C. Harding)

Pull request description:

  When signing a Taproot input (in a PSBT) using a key path spend we currently return the pubkey associated with key that signs. However it is common to think of the internal key as being the one that signs even though this is not technically true. We also have the internal key in the PSBT so matching against it is less surprising.

  When using the `Psbt` type to sign a Taproot input using a key path spend return the internal key.

  - Patch 1: Fix stale docs
  - Patch 2: Remove unnecessary panic
  - Patch 3: Change the key returned when signing Taproot input as key path spend

  Done as part of #2557, this is the release blocking part.

Enable internals "alloc" feature
We have 2 crates that require an allocator, `bitcoin` and `base58ck` -
these crates should enable the "alloc" feature when depending on
`internals`.

For `units` we use the `internals::error::InputString` but do not enable
the "alloc" feature - this is a bug, it means that the parsed string is
being lost from the error types that use `InputString`.

Enable "alloc" for `bitcoin`, `base58ck`, and `units`.

- `bitcoin` and `base56ck` is just for good measure so we don't get
  bitten later on.
- `units` is a bug fix and requires a point release.

Minimize usage of Network in public API
A release or so ago we added `non_exhaustive` to the `Network` enum,
this turned out to make usage of the enum un-ergonomic for downstream
users. After much debate we decided that a way forward was to just
minimize the usage of the enum in the public API by instead use
`AsRef<Params>` so that downstream could define their own network enum
based on the networks they support.

Minimize usage of `Network` by using `AsRef<Params>` as a parameter type
instead. "minimize" because the `Network` still appears in some places.

units: Improve re-exports
Make an attempt to improve the ergonomics and docs clarity of the
`units` crate.

- Don't inline error type re-exports, this keeps them up in the
"Re-exports" section and saves cluttering the other inlined docs.

- Re-export and inline the docs for `FeeRate` and `Weight` same as we do
for `Amount`. This makes the "Structs" section of the docs nice except
for the exclusion of the locktime types (which cannot be helped).

Use manual docs attributes
Currently we are using `Self` (in backticks) in the docs to functions
defined by the `do_iml` macro, this is a bit lazy, we can do better than
that.

Use `doc` attribute and the `$ty` macro variable to construct the docs
to use the type name.

- Use `U256` instead of `Self` or `self`
- Fix incorrect usage of `CompactTarget` [0]

[0] We knew this was wrong when we merged it but because the docs are
private we elected to do this follow up patch.

Pull request description:

  The `pow` types implement `fmt::LowerHex` but do not implement hex parsing.

  Add inherent methods `from_hex` and `from_prefixed_hex` to the  `pow` types - as we did for locktime types.

Add Magic::from_params
Currently `Magic` has per network consts but no way to dynamically get
the magic bytes for a network. Note also that we are currently trying to
reduce the usage of `Network` in the public API.

Add a public constructor to the `Magic` type that accepts a `Params`
parameter to determine the network to use.

units: Introduce public hex_u128 function
Introduce a function for parsing a `u128` from hex. Support strings with
and without a `0x` prefix as we do for `hex_u32`.

Introduce local variable
To make the stripping of the prefix a little clearer introduce a local
variable.

Refactor only, no logic changes.

Move helper function
Move the `strip_hex_prefix` helper function to below where it is called.
Note that I was the original author of this helper so there is no excuse
for it being above - bad Tobin no biscuit.

test: Add unit tests for hex_u32
Test the current behaviour of `hex_u32` - verifies that we handle
parsing strings with and without a prefix.

Pull request description:

  When computing the maximum difficulty transition threshold we forgot to check that the returned `Target` is not bigger than the maximum. This value is network specific so keep the original logic but with `_unchecked` on the function name.

  This was noted in the discussion on #2161

Improve API for max target threshold calculation
The maximum target threshold has a network dependant upper bound.
Currently we are not checking this bound. One complication is that there
is currently heated open debate around the `Network` type.

We can bypass the `Network` issue by using `AsRef<Params>` instead.

Add a function that does the checks based on the `Params` type as well
as an unchecked version.

Rename difficulty transition threshold functions
These two functions calculate the min/max threshold transition which is
a _target_ not a "difficulty" number. Using "difficulty" in the function
name is unnecessarily confusing.

Rename and deprecate the functions.
