Inline io module in io crate root
Its not immediately obvious why we nest the whole `io` code in an `io`
submodule within `lib.rs`. As far as I can tell we can inline it and
re-export from `rust-bitcoin` same as we do for our other dependencies.

This change would effect other users of the crate but since the `io`
crate is unreleased this effects no-one except us.

Matt Corallo 27c7c4e26a Add a `bitcoin_io` crate
In order to support standard (de)serialization of structs, the
`rust-bitcoin` ecosystem uses the standard `std::io::{Read,Write}`
traits. This works great for environments with `std`, however sadly
the `std::io` module has not yet been added to the `core` crate.

Thus, in `no-std`, the `rust-bitcoin` ecosystem has historically
used the `core2` crate to provide copies of the `std::io` module
without any major dependencies. Sadly, its one dependency,
`memchr`, recently broke our MSRV.

Worse, because we didn't want to take on any excess dependencies
for `std` builds, `rust-bitcoin` has had to have
mutually-exclusive `std` and `no-std` builds. This breaks general
assumptions about how features work in Rust, causing substantial
pain for applications far downstream of `rust-bitcoin` crates.

Here, we add a new `bitcoin_io` crate, making it an unconditional
dependency and using its `io` module in the in-repository crates
in place of `std::io` and `core2::io`. As it is not substantial
additional code, the `hashes` io implementations are no longer
feature-gated.

This doesn't actually accomplish anything on its own, only adding
the new crate which still depends on `core2`.

embedded: Remove error handler
Seems we no longer need an explicit error handler, remove it.

I did not grok the reason (long thread link below) but just removed it
and checked that the embedded crates still ran correctly.

Martin Habovstiak 06f1f027ab Make `hash_newtype` evocative of the output
The API guidelines say macro input should be evocative of the output.
`hash_newtype` didn't have this property.

This change makes it look exactly like the resulting struct, `$len`
parameter was removed since it's not needed, reversing is controlled
using an attribute. The macro is also better documented and ready to be
extended in the future.

The tagged SHA256 newtype is not yet modified because it has a more
complicated input parameters.

Closes #1648

Martin Habovstiak b018f3e90b Remove the `$len` argument from `hash_newtype`
Now that the `$len` argument is no longer used, remove it completely.

Martin Habovstiak 1b0988833a Remove `ToHex`
The `ToHex` trait was replaced by either simple `Display`/`LowerHex`
where appropriate or `DisplayHex` from `bitcoin_internals` which is
faster.

This change replaces the usages and removes the trait.

Tobin C. Harding b9643bf3e9 Import bitcoin_hashes crate into hashes
We would like to bring the `bitcoin_hashes` crate into the
`rust-bitcoin` repository.

Import `bitcoin_hashes` into `rust-bitocin/hashes`, doing so looses all
the commit history from the original crate but if we archive the
original repository then the history will be preserved. We maintain the
same version number obviously and in the changelog we note the change of
repository.

Commit hash that was tip of `bitcoin_hashes` at time of import:

 commit 54c16249e06cc6b7870c7fc07d90f489d82647c7

Includes making `embedded` and `fuzzing` per-crate i.e., move them into
`bitcoin` as hashes includes these also.

NOTE: Does _not_ enable fuzzing for `hashes` in CI.

Notes on CI:

Attempts to merge in the github actions from the hashes crate however reduces
coverage by not running hashes tests for beta toolchain. Some additional
work could be done to improve the CI to increase efficiency without
reducing coverage. Leaving for another day.
