crypto: blake2s - generic C library implementation and selftest
The C implementation was originally based on Samuel Neves' public
domain reference implementation but has since been heavily modified
for the kernel. We're able to do compile-time optimizations by moving
some scaffolding around the final function into the header file.

[ardb: - move from lib/zinc to lib/crypto
- remove simd handling
- rewrote selftest for better coverage
- use fixed digest length for blake2s_hmac() and rename to
blake2s256_hmac() ]
