Add a simple deserialization fuzz test for `PrefilledTransaction`.
Fixes: #460 (I think, I'm not sure if any of the other types need fuzzing?)

The `user_enum` macro is only used a single time. The macro includes
custom serde logic which can be trivially derived instead.
Remove the `user_enum` macro and just implement `Network` the old
fashioned way. Doing so simplifies the code.
We are attempting to flatten the `util` module; move the `bip32` module
to the crate root out of `util`.
Currently `src/util/` is ignored by the formatter, this patch does not
do formatting, will be done later.
The lock time methods are a source of endless confusion; make an attempt
at improving further the documentation on the two `is_implied_by`
methods (one on absolute lock time and one on relative).
As we just did for `absolute::LockTime` add a method `is_implied_by` and
deprecate `is_satisfied_by_lock`.
Reasoning: it is odd to think of a lock satisfying another lock but it
is clear to see that satisfaction of one lock can imply satisfaction of
another.
Recently we moved a few types from `transaction` to `sighash`, while
doing so I erroneously annotated code with the `deprecated` attribute
hoping it would give downstream users a gentle upgrade experience. It
turns out `deprecated` only works on functions.
During that same work, we re-exported from the crate root a bunch of
types from the `sighash` module that probably should not have been
re-exported. We are currently trying to create a nice clean API surface,
in an effort to move in the right direction we should remove the
re-exports and just re-export the `sighash` module.
Try to clean up the sighash export mess by doing:
- Remove the re-exports from the `transaction` module
- Remove crate level re-exports of `sighash` module types
- Re-export `sighash` module
Note, this patch is a breaking API change, justified by the fact that
there is no good way to gently lead downstream when moving types since
types cannot be deprecated with the `deprecated` attribute.
Done as part of flattening the `util` module.
We have a function in `util::misc` that operates on scripts, it is an
implementation of `FindAndDelete` from Bitcoin Core and is primarily
useful for supporting `CODESEPARATOR`, which we do not support.
Move the public `script_find_and_remove` function out of `util/misc.rs` and into
`util/mod.rs`, delete the testing and deprecate the function.

This example shows how to use the PSBT API for taproot transactions.
We have a simple BIP86-style spend and an example of an inheritance
timelock that can be spent either by the beneficiary via the script
path after a timelock, or via the key path by the benefactor so that
they can refresh the timelock at any time.

c4eb218cd0 schnorr:: Remove incorrect deprecated (Tobin C. Harding)
Pull request description:
We have a bunch of things deprecated since v0.28.0, I believe we agreed to deprecate for two release cycles so this stuff can all be deleted now.
- Patch one does the `schnorr` module; the deprecated attribute usage is just plain wrong (see https://github.com/rust-bitcoin/rust-bitcoin/discussions/1275). Also, in an attempt to make the API more ergonomic, patch one adds re-exports of secp types.
- Patch 2 deletes all other code deprecated since v0.28.0

1bf885550e Redesign `hex::BufEncoder` to accept owned arrays (Martin Habovstiak)
Pull request description:
Not being able to create an owned `BufEncoder` prevented returning it from functions which need to allocate the buffer on stack. Such is the case in WIP serde via consensus serialzation.
This change refactors `OutBytes` to be unsized, adds an `AsOutBytes` trait and uses that one instead of `Into` to perform the conversion.

Currently we attempt to have deprecated key types in the `schnorr`
module. The `deprecated` attribute does not work on types, only on
functions.
Remove the broken deprecation logic and re-export key types instead of
using type alias', this allows a bunch of qualified paths to be
simplified also.
Add `pub use` re-exports of all secp256k1 types that are part of the
public API of the `schnorr` module. This makes the module more ergonomic
to use.

When filtering it is necessary to check two lock times against each
other, we currently provide a patter for doing so in the docs but we can
do better.
It was observed that satisfaction of a lock time 'implies' satisfaction
of another lock time if the lock times are the same unit and one locks
value is less than the others - this is exactly the code pattern we
suggest for filtering.
Add a method on `absolute::LockTime` for checking a lock against another
lock, add rustdoc comment explaining the methods function in filtering
prospective lock time values (how we use it in `rust-miniscript`).
Not being able to create an owned `BufEncoder` prevented returning it
from functions which need to allocate the buffer on stack. Such is the
case in WIP serde via consensus serialzation.

`Cargo.toml` claimed that this crate works with very old versions of `serde` which wasn't the case. This commit changes the versions to minimal known-to-work values.
Adding `trivial` tag because the text change is trivial even though figuring it out wasn't. :)
If you manually decrease any of the versions by 1 (in both `Cargo.toml` and `Cargo.lock`) the build should fail.

040b14ef1a Implement basic support for fast hex encoding (Martin Habovstiak)
Pull request description:
There's a `hex` module in `bitcoin_hashes` which is a bit out of place and not very fast - it passes each *digit* through dynamic dispatch not only adding overhead but also not allowing `String` to make better allocations.
This change adds basic support for hex encoding using a stack-allocated buffer which minimizes the overhead of dynamic dispatch. It also provides a new `DisplayHex` trait designed to replace `ToHex` found in `bitcoin_hashes`.

Currently in one of the rustdoc examples showing lock satisfaction we
use two locks with the same value, this obfuscates which lock is doing
the satisfying and which lock is being satisfied.
Increment the value in one of the locks so it is obvious which lock is
which.

### Notes
This PR uses a `path` dependency which means `rust-bitcoin` cannot be released in its current state, will need to be changed once we release the `bitcoin-internals` crate on `crates.io`.
Please note also the testing strategy imposed by this PR - each new crate to have its own `contrib/test.sh` run from the top level `test.sh`.
Please excuse the mid-series import statement refactor, I had a moment of weakness and got uncontrollably triggered by the messy imports in one file, I managed to keep myself together on the others :)

Create a directory `bitcoin` and move into it the following as is with
no code changes:
- src
- Cargo.toml
- contrib
- test_data
- examples
Then do:
- Add a workspace to the repository root directory.
- Add the newly created `bitcoin` crate to the workspace.
- Exclude `fuzz` and `embedded` crates from the workspace.
- Add a contrib/test.sh script that runs contrib/test.sh in each
sub-crate
- Fix the bitcoin/contrib/test.sh script
