1. "unsigned long long" isn't portable changed: to BN_ULLONG.
2. The LL prefix isn't allowed in VC++ but it isn't needed where it is used.
2. Avoid lots of compiler warnings about signed/unsigned mismatches.
3. Include new library directory pqueue in mk1mf build system.
4. Update symbols.

sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.

I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.

codebase apparently was inconsistent.  And crypto/Makefile.ssl
*does* need an ERRC ..

script, translates function codes better and doesn't need the K&R function
prototypes to work (NB. the K&R prototypes can't be wiped just yet: they are
still needed by the DEF generator...). I also ran the script with the -rewrite
option to update all the header and source files.
