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.

1. The already released version was 0.9.1c and not 0.9.1b

2. The next release should be 0.9.2 and not 0.9.1d, because
   first the changes are already too large, second we should avoid any more
   0.9.1x confusions and third, the Apache version semantics of
   VERSION.REVISION.PATCHLEVEL for the version string is reasonable (and here
   .2 is already just a patchlevel and not major change).
