openpgp-ffi: New crate.

  - This creates a new crate, 'sequoia-openpgp-ffi', and moves a
    handful of functions from 'sequoia-ffi' to it.

  - The 'sequoia-ffi' crate is a superset of the 'sequoia-openpgp-ffi'
    crate.  This is accomplished by some include! magic.

  - My first attempt involved having 'sequoia-ffi' depend on
    'sequoia-openpgp-ffi', so that the former just re-exports the
    symbols.  However, that turned out to be unreliable, and might be
    not what we want, because it could also duplicate parts of Rust's
    standard library.

  - Fixes #144.
