Great. It's amazing how you are able to speedup various formats. Please 
keep up the good work!

I also made changes to the all of the length setters, to place a 0x80 in any sse2 buffers at the proper location.  These 0x80 bytes were only being placed into the sse buffers for certain lengths.

BTW are flags MGF_SALTED and MGF_USERNAME really useful? If format uses 
something like DynamicFunc__append_salt then it's surely salted 
otherwise it's not. The same with username.
