New wrapper macro for printf("%zu"), for old VS compat.

Browse Source 
A user reports that Visual Studio 2013 and earlier have printf
implementations in their C library that don't support the 'z' modifier
to indicate that an integer argument is size_t. The 'I' modifier
apparently works in place of it.

To avoid littering ifdefs everywhere, I've invented my own inttypes.h
style macros to wrap size_t formatting directives, which are defined
to %zu and %zx normally, or %Iu and %Ix in old-VS mode. Those are in
defs.h, and they're used everywhere that a %z might otherwise get into
the Windows build.
