Patch adds Bernstein's Poly1305 message authentication code to libgcrypt.
Implementation is based on Andrew Moon's public domain implementation
from: https://github.com/floodyberry/poly1305-opt
The algorithm added by this patch is the plain Poly1305 without AES and
takes 32-bit key that must not be reused.
