725d9af94a Lib: Add Blake2s and Blake2b hash functions
The Babel MAC authentication RFC recommends implementing Blake2s as one of
the supported algorithms. In order to achieve do this, add the blake2b and
blake2s hash functions for MAC authentication. The hashing function
implementations are the reference implementations from blake2.net.

The Blake2 algorithms allow specifying an arbitrary output size, and the
Babel MAC spec says to implement Blake2s with 128-bit output. To satisfy
this, we add two different variants of each of the algorithms, one using
the default size (256 bits for Blake2s, 512 bits for Blake2b), and one
using half the default output size.

Update to BIRD coding style done by committer.

de2a27e255 Add generic message authentication interface
Add generic interface for generating and verifying MACs (message
authentication codes). Replace multiple HMAC implementation with
a generic one.
