Subject: raw-md5 valid() & split() optimization

magnum -

Attached are my current raw-md5 changes, including a recent optimization
to valid() and split() that speeds up loading of the 29M hashes from 21+
to under 20 seconds.  Total for Fred's testcase is:

real    0m44.034s
user    3m3.369s
sys     0m18.963s

We might want to make similar changes to valid() and split() of other
common fast hashes.  And review their binary() while at it.  raw-md5's
binary() looked sane to me performance-wise.
