Subject: Re: Unused global symbols in jumbo

I made the MD5crypt helper functions in sse-intrinsics.c static, which made no difference in itself. So I also added MAYBE_INLINE. There was a 1-2% boost from that here.

Thus, we have #defines in each source, which mangles the normal name (crypt) into something unique to the format  (MD5Gen_crypt, etc).  Yes, they are globals, but steps have been taken to make sure they are linker safe.
