cem e9bcf6874b Add xform-conforming auth_hash wrapper for Poly-1305
The wrapper is a thin shim around libsodium's Poly-1305 implementation.  For
now, we just use the C algorithm and do not attempt to build the
SSE-optimized variant for x86 processors.

The algorithm support has not yet been plumbed through cryptodev, or added
to cryptosoft.
