b84e1d46c0 Move amount module out of util (Tobin C. Harding)
Pull request description:
Done as part of flattening the `util` module. Simply move the `amount` module out of the `util` module and to the crate root. Justified by the fact that the `Amount` type is more-or-less a "primitive" bitcoin type.

The `util::hash` module provides two functions for computing a merkle
root from a list/iterator of hashes.
Rename the module to `merkle_root` and move it to the crate root,
deprecate the original functions.

dea9b1d1e0 Re-export base64 when enabled (Alekos Filini)
Pull request description:
`base64` used to be exported until commit 23ee0930c7 which removed the `pub extern crate` declaration.

`default-features = false` was missing previously but blindly adding it
would lead to subtle risk of breaking when a crate not needing `std`
depends on `bitcoinconsensus` and simultaneously another crate not
needing `bitcoinconsensus` depends on `std` and another crate depends on
them both.
This change fixes it by introducing `bitcoinconsensus-std` feature flag
and provides a fallback if the flag is off. Unfortunately the fallback
has to use a bit of reasonable `unsafe` due to limitations of upcasting.
The only safe alternatives are not do it and provide worse experience
for crates that are affected by the problem above or break the API,
which couldn't be backported and would be more annoying to use.

Done as part of the effort to flatten the `util` module.
The `sighash` module can stand alone in the crate root, it provides a
discreet set of functionality - the `SighashCache` and associated types.

We are attempting to flatten the `util` module; move the `bip152` module
to the crate root out of `util`.
Currently `src/util/` is ignored by the formatter so this move causes
the `bip152` module to be formatted.
Currently we use the `Uint256` type to represent two proof of work
integers, namely target and difficulty (work).
It would be nice to not have a public integer type that is not fully
implemented (i.e., does not implement arithmetic etc as do integer types
in stdlib). Instead of implementing all the stdlib functions we can
instead add two new wrapper types, since these are not general purpose
integers they do not need to implement anything we do not need to use.
- Add a `pow` module.
- Put a modified version of `Uint256` to `pow`.
- Add two new wrapper types `Target` and `Difficulty`.
- Only implement methods that we use on each type.
Note this patch does not remove the original `Uint256`, that will be
done as a separate patch.

041d6a8097 Move and deprecate script_find_and_remove (Tobin C. Harding)
Pull request description:
Done as part of [flattening util](https://github.com/rust-bitcoin/rust-bitcoin/issues/639).
Move some code out of `misc` then re-name the module to `signature` and move it to the crate root.
- Patch 1: Move a single public function, needs review that destination module is ok. I did consider re-naming the function to remove `script_` prefix but decided to leave it as is.
- Patch 2: Re-names `misc` -> `signature` and puts it in the crate root
- Patch 3: Runs the formatter on `signature` module
All changes include deprecated re-exports.

2001f44e46 Try to fix up sighash export mess (Tobin C. Harding)
Pull request description:
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.

We are attempting to flatten the `util` module; move the `bip32` module

Currently `src/util/` is ignored by the formatter, this patch does not
do formatting, will be done later.

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.
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
