Adopt the new hash API functions where they're useful.

This commit switches as many ssh_hash_free / ssh_hash_new pairs as
possible to reuse the previous hash object via ssh_hash_reset. Also a
few other cleanups: use the wrapper function hash_simple() where
possible, and I've also introduced ssh_hash_digest_nondestructive()
and switched to that where possible as well.
