Make the Transform functions match the other hash types and document them.
Use sizeof() in the Init functions where it makes sense.
Use weak aliases instead of wrapper functions.
Probably should have gone in before the major bump but as these are only
used internally by the sha2 functions themselves there should be no problem.
