g_printf_string_upper_bound (#50217)

[Shawn T Amundson <amundson eventloop com>]

Is g_strdup_vprintf supposed to work the same cross-platform?

If so, shouldn't g_printf_string_upper_bound simply conform to 
ISO C instead of handling non-ISO C additions?  

If not, should there be two versions - a glibc-based version and
a ISO C version.  The ISO C version could print warnings if
non-ISO C additions were used on a non-glibc operating system.
