crypto: blake2b - add blake2b generic implementation
The patch brings support of several BLAKE2 variants (2b with various digest lengths). The keyed digest is supported, using tfm->setkey call. The in-tree user will be btrfs (for checksumming), we're going to use the BLAKE2b-256 variant. The code is reference implementation taken from the official sources and modified in terms of kernel coding style (whitespace, comments, uintXX_t -> uXX types, removed unused prototypes and #ifdefs, removed testing code, changed secure_zero_memory -> memzero_explicit, used own helpers for unaligned reads/writes and rotations). Further changes removed sanity checks of key length or output size, these values are verified in the crypto API callbacks or hardcoded in shash_alg and not exposed to users.
