Add nd_{v}snprintf() routines/wrappers.

Some versions of the MSVC runtime library have a non-C99-compliant
vsnprintf(), which we want to avoid.  On Windows, use snprintf() and
vsnprintf() for VS 2015 and later, where they both exist in
C99-compliant forms, and wrap _{v}snprintf_s() otherwise (they're
guaranteed to do the null termination that we want).
