brian m. carlson 4b4e291809 hash: add an SHA-256 implementation using OpenSSL ...

We already have OpenSSL routines available for SHA-1, so add routines
for SHA-256 as well.

On a Core i7-6600U, this SHA-256 implementation compares favorably to
the SHA1DC SHA-1 implementation:

SHA-1: 157 MiB/s (64 byte chunks); 337 MiB/s (16 KiB chunks)
SHA-256: 165 MiB/s (64 byte chunks); 408 MiB/s (16 KiB chunks)
