Mark Johnston 9b1d87286c ossl: Add a fallback AES-GCM implementation using AES-NI
This lets one use ossl(4) for AES-GCM operations on contemporary amd64
platforms.  A kernel benchmark indicates that this gives roughly
equivalent throughput to aesni(4) for various buffer sizes.

Bulk processing is done in aesni-gcm-x86_64.S, the rest is handled in a
C wrapper ported from OpenSSL's gcm128.c.
