relative locktime: add is_implied_by method for sequences
This gives a way to determine whether a CSV will pass, given a sequence
number, in a type-safe way where you can't get the two things backward.

relative locktime: add "obvious" constructors
Adds constructors to allow directly creating locktimes from time or
block counts; adds a flooring constructor to Time to match the ceiling
one; adds an explicit constructor to Height since the From<u16> was not
very discoverable.

Refactor witness_version and is_witness_program
These two functions are related. We cannot, by definition, get the
witness version from a script that is not a witness program but
currently the code is not linking these two things.

Refactor by doing:

- Move the check of the witness program bip rules to `witness_version`
- Call `witness_version().is_some()` in the predicate

Improve the docs while we are at it to include the bip text in the
rustdoc. Note I didn't bother referencing the segwit bip number, this
bip text is pretty well known.

Add unit tests for shortest/longest witness program
Add two unit tests that verify we can correctly determine if a
shortest allowed and longest allowed script is a witness program.

Done in preparation for patching the `witness_version` function.

hashes: Bump version to v0.14.0
In preparation for release add a changlelog entry and bump the version.

I'm not 100% sure that this release is API breaking, dependencies
definitely changed. The rest might be only additives but I didn't bother
looking exactly because I think its better to bump the minor version and
err on the side of caution.

Note the hashes 0.13.0 dependency stays in the dependency graph because
of secp, we can update secp after releasing `hashes` then update the
secp dependency in `rust-bitcoin` thereby removing the `hashes v0.13.0`
dependency - phew.

Hide base58::Error internals

bitcoin: Stop using base58 errors
We are currently using the `base58::Error` type to create errors in
`bitcoin`, these are bitcoin errors not `base58` errors.

Note that we add what looks like duplicate
`InvalidBase58PayloadLengthError` types but they are different because
of the expected length. This could have been a field but I elected not
to do so for two reasons:

1. We will need to do so anyways if we crate smash more
2. The `crypto::key` one can have one of two values 33 or 34.

With this applied we can remove the now unused error variants from
`base58::Error`.

Pull request description:

  This can be checked against the 0.29.x branch, and against the commit prior to #1659 (40c246743b^) and you will see that it is consistent EXCEPT:

  * In rust-bitcoin 0.29.x we did not have multiple sighash types, only `Sighash`; we now have `LegacySighash`, `SegwitV0Sighash`, and `TapSighash`.
  * In #1565 we deliberately changed the display direction of the sighashes, to match BIP 143.

Pull request description:

  Also move the `parse` module as well as constants as required.

  - Feature gate on "alloc" as needed.
  - Remove rustdocs that use `bitcoin` types.
  - Re-export units types so this is a non-breaking change.
  - Fix import paths.

Merge rust-bitcoin/rust-bitcoin#2458: Support signing taproot in psbt
41e8fb0863 Support signing taproot in psbt (yu)

Pull request description:

  Hi team, I'm from Keystone Wallet team. currently rust-bitcoin does not support signing taproot transactions in psbt.
  We think this founction should be included in the psbt module, we submit this PR. Some context and discussion about this PR can be found here: #2418.

  For this PR, mostly two new functions are introduced:

  - `bip32_sign_schnorr`:  sign a taproot input.
  - `sighash_taproot`: calculate the sighash message to sign a taproot input along with the sighash type.

  Looking forward to your feedback.

CI: Disable MSAN job
I believe there is currently a bug in the MemorySanitizer, when we pass
various types across the FFI boundry MSAN gives a unititialized variable
error:

- `usize` passed as `size_t` (cannot be uninitialized)
- byte slice passed as `const char *`

In order to let other work continue disable the MSAN job.

io: Bump version to 0.1.2
There have only been two PRs merged that touched the `io` crate since it
as last released. The changes are additive so we can do a pre-0.1 point
release.

In preparation for release bump the version and add a changelog entry.

Merge rust-bitcoin/rust-bitcoin#2576: Return error when constructing pubkey from slice
6ecc41d126 Return error when constructing pubkey from slice (Tobin C. Harding)

Pull request description:

  This PR fixes a bug introduced by me in #2473, and uncovered by #2563 - amazing that it was found so quickly!

  Constructing a pubkey using `PublicKey::from_slice` can fail for reasons other than just incorrect length - we should not be using `expect` but rather returning the error.

  A purist might argue that we are now returning a nested error type with an unreachable variant:

    `ParsePublicKeyError::Encoding(FromSliceError::InvalidLength)`

  Is this acceptable or do we want to further improve this?

Document how to write commits
Reviewers often find themselves linking to blog posts to encourage newer
devs to improve their commit logs, we can save everyones time by putting
the links in the contributing docs, then we can just point devs there.

Implement consensus deserialize_hex
We have `serialize_hex` and `deserialize` but no `deserialize_hex`, add it.

Move the `IterReader` out of `consensus::serde` to the `consensus`
module.

Add some additional logic to the `DecodeError`, I'm not sure why this
wasn't there before?

Use the `HexSliceToBytesIter` by way of the `IterReader` to deserialize
an arbitrary hex string. Add unit tests to check that we consume all
bytes when deserializing a fixed size object (a transaction).

Merge rust-bitcoin/rust-bitcoin#2565: Removes txid prefix in transaction IDs
56132f59d5     Remove the `:#` formatting for `hex_fmt_impl` macro (448 OG)

Pull request description:

  This commit attempts to solve #2505  by ensuring that formatting is not forced using the `:#` in the hex macro code generating in macro rule `hex_fmt_impl` in the hashes/utils.rs file.

  The write! macro forces all formatting to add the prefix `0x` by adding an alternate by (#) default

  ```rust
  impl<$($gen: $gent),*> $crate::_export::_core::fmt::Debug for $ty<$($gen),*> {
              #[inline]
              fn fmt(&self, f: &mut $crate::_export::_core::fmt::Formatter) -> $crate::_export::_core::fmt::Result {
                  write!(f, "{:#}", self) // <-- This is where the formatting is being forced.
              }
          }
  ```

  By removing this formatting, the `:#` must be specified by the user in order for a prefix to be added.

  ```rust
  let outpoint = bitcoin::OutPoint::default();
      println!("{:?}", &outpoint);
      println!("{:#?}", &outpoint);
      println!("{:#}", &outpoint);
      println!("{:x}", &outpoint.txid);
      // `{:#}` must be specified to pretty print with a prefix
      println!("{:#}", &outpoint.txid);
      dbg!(&outpoint);
      dbg!(&outpoint.txid);
  ```

  The PR also adds testcase for this when running `cargo test` .
