Remove the ffi crates.

  - Remove the general-purpose ffi crates.  They will be moved into
    their own repository.  Note that we consider general-purpose ffi
    crates to be a dead end: exposing Sequoia's interface requires a
    large number of types and functions, and using the interface from
    C turned out to be verbose and error-prone.  Instead, we prefer to
    write point solutions in Rust that implement exactly the
    functionality the downstream consumer needs, then expose this via
    ffi bindings.
