Make the various printf feature test macros reflect the system printf,

	* configure.in: Make the various printf feature test macros
	reflect the system printf, even when using the included printf.
	In particular, don't force HAVE_C99_SNPRINTF, since g-gnulib.h
	needs that test result.  (#122973)

	* glib/gprintf.c (g_vasprintf): Don't rely on HAVE_VASPRINTF,
	directly check for _g_vasprintf.

	* glib/gprintfint.h (_g_vasprintf): Only define _g_vasprintf()
	if vasprintf() is available.

	* glib/gnulib/printf.c (_g_gnulib_vfprintf): Don't write
	trailing nul to the file. (#122973)

	* acinclude.m4 (AC_FUNC_VSNPRINTF_C99): Make the test
	detect non-C99-compliance of AIX 5.1 and Solaris
	vsnprintf().  (#122496)

remaining functions in the printf family based on
vasnprintf. g-gnulib.h is included by all source files in order to
move all exported functions to the _g_gnulib namespace, replace malloc
by g_malloc and make sure that snprintf is only used if it implements
C99 return value semantics.
