Because I want to be able to fall back from an ahash to shash in
the middle of a hash, i.e., I need to be able to export from the
ahash, import it into an shash, and then continue hashing.

Because I've already changed the shash export format to use a
generic partial buffer for all algorithms and it's not the same
as struct sha256_state.
