Re-exports types from the toplevel instead of placing them in individual
modules (often which only contain one type).
This makes the API easier for users to navigate, while still retaining
the same module structure internally.
Additionally, this commit uses the `uuid` crate for modeling UUIDs.
Adds a `yubikey::Result` alias with `yubikey::Error` as the error type.
Since we only have one `Error` type, this simplifies the return types
where a `Result` is returned.
Renames the following to match Rust idioms:
- `APDU` => `Apdu`
- `CCC` => `Ccc`
- `CHUID` => `ChuId`
Also removes `Copy` from `mscmap::Container`, which fixes a clippy lint
about its usage of `to_bytes`.
This commit contains a "big bang" refactor/rewrite which does the
following:
- Replaces all `SCard*` FFI calls with the `pcsc` crate, which provides
a safe, portable PC/SC API across Windows, macOS, and Linux
- Refactors the `util` module into modules representing the various
device functions and concepts, e.g. `certificate`, `key`, `mgm`
- Replaces all usage of `libc` with `std` functionality, and in many
places rewriting functionality to use safe code.
- Removes `ykpiv_` from all function names, and `Piv*` from type names.
In 20/20 hindsight I wish I had done this commit more incrementally so
as to make it easier to review. Que sera sera.
However, realistically we need to test all functionality on the device
to ensure that it actually works. Going forward I would like to put
pretty much all of the current code behind an `untested` cargo feature,
and then remove it for each bit of functionality we test.
