Add test vectors from RFC 6234 for SHA-1 and SHA-2.

Browse Source 
This supersedes the '#ifdef TEST' main programs in sshsh256.c and
sshsh512.c. Now there's no need to build those test programs manually
on the rare occasion of modifying the hash implementations; instead
testcrypt is built every night and will run these test vectors.

RFC 6234 has some test vectors for HMAC-SHA-* as well, so I've
included the ones applicable to this implementation.
