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.

move some functions from exported header <openssl/dtl1.h> into "ssl_locl.h";
fix silly indentation (a TAB is *not* always 4 spaces)
