Stop using deprecated OutPoint functions
Either our CI is failing us or `deprecated` does not work as expected,
either way we should not be using the `OutPoint::null()` or `is_null`
functions any more because we deprecated them already.

Pull request description:

  - Re-write the function to reduce the error cases returned.

a20d0bc4eb Deprecate `from_slice()` in sha256.rs (Jamil Lambert, PhD)
089043546f Deprecate `from_slice` methods in favor of arrays (Jamil Lambert, PhD)

Pull request description:

  As brought up in issue #3102 support for Rust arrays is now much better so slice-accepting methods that require a fixed length can be replaced with a method that accepts an array.

  `from_slice()` methods that require a fixed length have been deprecated and where needed a `from_byte_array()` method created that accepts an array.

  There are still `from_slice` methods that rely on changes to external crates before they can be changed to arrays.

Introduce and use new compact_size module
We would like to move the witness module to `primitives` but there is
a bunch of usage of `VarInt`.

Introduce a module that does the encoding and decoding instead, this
code is internal so put it in `internals`.

Note we add an unused public `MAX_ENCODABLE_SIZE` variable that is
commented with an issue link. Done like this because its quite
important that we see to it and it makes it clear that we are not and
we know about it.

Merge rust-bitcoin/rust-bitcoin#3278: Show compressed public key in Debug for CompressedPublicKey
9db6234ea9 Show compressed public key in Debug for CompressedPublicKey (Jiri Jakes)

Pull request description:

  Currently `CompressedPublicKey` debug produces output of form:

  ```
  CompressedPublicKey(PublicKey(2f8b18dc0adcb73d75f7934d9523ea7347083e41c48115398cb37e295a0a6ffe86e0bf8b1ef65888c880c8d8813a30e69e466380cbe2daec18f3ed1e7a553ff2))
  ```

  Although it shows real internal structure together with inner uncompressed public key, it is not too helpful for the purpose of debugging _compressed_ public key.

  After this patch, `Debug` output will be equal to `Display` (it, in fact, delegates rendering to `Display`), prepended by the name of the struct:

  ```
  CompressedPublicKey(02fe6f0a5a297eb38c391581c4413e084773ea23954d93f7753db7dc0adc188b2f)

  - feature gate tests behind the `alloc` feature if they use anything from the alloc crate (like the `format!` macro)
  - `schemars` feature enables `alloc` because (for example) its trait wants implementations to return `String`
  - fix `bitcoin-io` always enabling when `std` is enabled (only useful if people depend on `hashes` only, `bitcoin` depends on `bitcoin-io` already)

Merge rust-bitcoin/rust-bitcoin#3255: fix: re-implement `Psbt` (de)serialization from/to readers/writers
cf129ad314 fix: re-implement (de)serialization from/to readers/writers (elsirion)

Pull request description:

  Fixes #3250.

  The serialization is less than ideal and still allocates a lot. I can understand not wanting to (ab)use the consensus encoding traits, but they have a pretty good interface, copying it and creating some `EncodePsbt` and `DecodePsbt` traits with similar interfaces would have been nice imo.

Pull request description:

  As mentioned in issue #3234 `s.parse::<T>()` is more idiomatic and produces more helpful error messages.

  This has been changed in the main codebase, not including examples, rustdocs, and in the `test` modules.

  `use std::str::FromStr;` has been removed where this change makes it unnecessary.

  To close the issue it may also need to be changed in the examples and the `test` modules and `contributing.md` updated.

Pull request description:

  Adds an example draft showing what is needed to use Arbitrary for coin selection.

  Shot out to how nice Arbitrary is for fuzzing a target by taking unstructured randomness and creating structured rust-bitcoin types for fuzzing.  Is there a way we could add this to rust-bitcoin for structuring the fuzz data needed?

  This is then the example to fuzz test a SRD algo (after applying this PR to rust-bitcoin) using rust-bitcoin types :)

  ```
  #![no_main]

  use arbitrary::Arbitrary;
  use bitcoin::{Amount, FeeRate};
  use bitcoin_coin_selection::{select_coins_srd, WeightedUtxo};
  use libfuzzer_sys::fuzz_target;
  use rand::thread_rng;

  #[derive(Arbitrary, Debug)]
  pub struct Params {
      target: Amount,
      fee_rate: FeeRate,
      weighted_utxos: Vec<WeightedUtxo>,
  }

  fuzz_target!(|params: Params| {
      let Params { target: t, fee_rate: f, weighted_utxos: wu } = params;
      select_coins_srd(t, f, &wu, &mut thread_rng());

  There are a couple of issues around the ECDSA signature decoding / parsing code. We have duplicate code in `from_str` and `from_slice` and both use the same error type even though it is impossible to get a hex error in `from_slice`.

  Create two errors:

  Call through to `from_slice` after parsing hex into a byte vector.

Reduce API surface of tagged wrapped hash types
Recently we made it so that wrapper types created with `hash_newtype`
were not general purpose hash types i.e., one could not easily hash
arbitrary data into them. We would like to do the same for tagged
wrapped hash types.

In `hashes` do:

- Create a new macro `sha256t_tag` that does just the tag/engine stuff
out of the `sha256t_hash_newtype` macro.
- Deprecate the `sha256t_hash_newtype` macro.

In `bitcoin` do:

- Use a combination of `sha256t_tag` and `hash_newtype` to create tagged
wrapped hash types.

Note that we do not add private helper functions `engine` and
`from_engine` to the tagged wrapper types as we do for legacy/segwit in
`sighash`. Can be done later if wanted/needed.

Wrap CompactTarget impl block in temporary module
`rustfmt` is unable to format macro calls so instead we wrap the impl
blocks in a module to enable formatting in the next commit.

Separate CompactTarget impl blocks
In preparation for adding an `CompactTargetExt` trait move the

Remove generic test impl
In preparation for moving the `CompactTarget` to `primitives` remove the
generic `Into` impl and explicitly implement for just the `From` impls
that the `pow` unit tests use.

Test code only.

Martin Habovstiak fcc3cb03f0 Support non-doc attrs in extension trait macro
The `define_extension_trait` macro originally didn't support `#[inline]`
or other attributes for simplicity. We still want them so this commit
adds basic support for it. It adds the `doc` attributes to trait
*definition* only and adds all other attributes to the *implementation*
only. This should support `#[inline]` and other attributes. The downside
is it doesn't support adding non-doc attributes to trait *definition*
but I can't think of any relevant ones that we would want and we can
find a solution later if we do.

We want to move `Script` as a plain old data type to `primitives`.

Step 1: Move the methods that will go to `primitives` to a separate impl
block.

Merge rust-bitcoin/rust-bitcoin#3137: De-sugar `self`
34e8212594 Replace &self with self: &Self (Tobin C. Harding)

Pull request description:

  `foo(&self)` is syntax sugar for `foo(self: &Self)`.

  The `define_extension_trait` is currently large, ugly, and not that expressive. If we use `self: &Self` then the macro is greatly simplified.

  (Also consuming version `self: Self`)

  De-sugar only, no logic changes.

Merge rust-bitcoin/rust-bitcoin#2929: Introduce `ToU64` trait
579b76b7cb Introduce ToU64 conversion trait (Tobin C. Harding)

Pull request description:

  The idea for this was pulled out of Steven's work in #2133

  We already explicitly do not support 16 bit machines.

  Also, because Rust supports `u182`s one cannot infallibly convert from a `usize` to a `u64`. This is unergonomic and results in a ton of casts.

  We can instead limit our code to running only on machines where `usize` is less that or equal to 64 bits then the infallible conversion is possible.

  Since 128 bit machines are not a thing yet this does not in reality introduce any limitations on the library.

  Add a "private" trait to the `internals` crate to do infallible conversion to a `u64` from `usize`.

  Implement it for all unsigned integers smaller than `u64` as well so we have the option to use the trait instead of `u32::from(foo)`.

  The `PushBytes` type enforces len is less than 0x100000000 so we do not need to panic in a catch all pattern after explicitly matching against less than 0x100000000.
