[PATCH net-next v3 07/17] zinc: Poly1305 generic C implementations and selftest

["Jason A. Donenfeld" <Jason@zx2c4.com>]

These two C implementations -- a 32x32 one and a 64x64 one, depending on
the platform -- come from Andrew Moon's public domain poly1305-donna
portable code, modified for usage in the kernel and for usage with
accelerated primitives.
