Fix various stuff: that VC++ 5.0 chokes on:

1. Add *lots* of missing prototypes for static ssl functions.
2. VC++ doesn't understand the 'LL' suffix for 64 bits constants: change bn.org
3. Add a few missing prototypes in pem.org
Fix mk1mf.pl so it outputs a Makefile that doesn't choke Win95.
Fix mkdef.pl so it doesn't truncate longer names.
