This series removes the nhpoly1305 crypto_shash algorithm, which existed
only to fit Adiantum hashing into the traditional Linux crypto API
paradigm. It replaces it with an nh() library function, combined with
code in the "adiantum" template that handles the Poly1305 step.
The result is simpler code. As usual, I've also fixed the issue where
the architecture-optimized code was disabled by default.
I've also included some additional cleanups for the Adiantum code.
I'm planning to take this via libcrypto-next.
