Adding Snprintf() and Vsnprintf() to nbase/nbase_str.c. This is because of Windows' stupid implementation where it doesn't write a NULL byte at the end of the buffer if the result is truncated. I would've just #defined snprintf and vsnprintf to some wrapper function for Windows, but this doesn't work as libdnet and libpcap (and libpcap includes under mswin32) define snprintf to _snprintf and vsnprintf to _vsnprintf like we do, and through the many defines they end up being available in the Nmap sources. Vsnprintf() uses vsnprintf() (and writes a NULL byte at the end if truncated), and Snprintf uses Vsnprintf().
