Andrey Semashev be8790115c Added portable snprintf/vsnprintf definition. ...

This definitions is mostly a workaround for older MSVC versions that only
provided non-portable _snprintf etc. that are not fully conforming to
the standard snprintf. This implementation fixes its issues wrt. null
termination and returned values in case of buffer overflows.

On platforms that support the standard snprintf, the definitions in
the header are equivalent to the standard functions.
