Pushed to GitHub now, both sha-crypt256 and sha-crypt512. I didn't find
much to optimise, it's spending over 95% in the OpenSSL functions. But
OMP should scale well (I only tested two cores).

crypt_all() and rounds parsing are pretty close copies of the reference
code. Self-tests are the same that existed in crypt_fmt.c. I stole a
little base64 convenience from MD5_std.c too.
