Add support for HMAC-SHA-256 and HMAC-SHA-512.

Browse Source 
Implement support for these algorithms and wire them up to the libgcrypt
and OpenSSL backends.  Increase the maximum MAC buffer size to 64 bytes
to prevent buffer overflows.  Prefer HMAC-SHA-256 over HMAC-SHA-512, and
that over HMAC-SHA-1, as OpenSSH does.

Closes #40
