8f3cc4a9bf Add support for HMAC-SHA-256 as an SSH-2 MAC algorithm ("hmac-sha2-256") 
as specified in RFC 6668.  This is not so much because I think it's 
necessary, but because scrypt uses HMAC-SHA-256 and once we've got it we 
may as well use it.

Code very closely derived from the HMAC-SHA-1 code.

Tested against OpenSSH 5.9p1 Debian-5ubuntu1.

8d0c333946 SHA-256 implementation, for use in future KEX algorithms, in particular 
diffie-hellman-group-exchange-sha256, which the last DHGEX draft defined.
Code lifted from Simon's "crypto" directory, with changes to make it look
more like sshsh512.c.
