Add a build target for MSVC 2013
Apparently it is desired to keep this on life support.
So we add a build target for this non-C99 platform, and
provide internal versions of snprintf and vsnprintf for use
only on this platform that match the C99 semantics.
This allows us to use C99 semantics normally elsewhere.
