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
Currently the generic iterators in `bip158` return items of type slice
reference. We can make the code cleaner (no explicit lifetimes) and more
general if the generic iterator argument iterates over `Borrow<[u8]>`.
Note, includes adding `Borrow` to `crate::prelude`.
We are attempting to flatten the `util` module; move the `bip158` module
to the crate root out of `util`.
Currently `src/util/` is ignored by the formatter so this move causes
the `bip32` module to be formatted.
