I just committed reduced binary size for raw-md4/md5/sha1 and nt2. Saves
3 or 4 bytes per loaded hash (makes some difference for 135 million
hashes, lol) and should help keeping good stuff in cache. It's not
merged to bleeding yet - the get_source() gets a little trickier and I
should get some sleep.
It passes Test Suite - actually I would have committed a hideous bug in
SHA-1 if it wasn't for TS.
