Call setlocale (LC_ALL, ""). (#60606)

Wed Oct 10 12:48:38 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkmain.c (gtk_init_check): Call setlocale (LC_ALL, "").
	(#60606)

	* gtk/gtkmain.c (gtk_disable_setlocale): Add function
	to disable calling setlocale (LC_ALL, "").

	* gtk/gtkmain.c (gtk_set_locale): Indicate in the
	docs that this function is not typically useful.

	* gdk/x11/{gdkim-x11.c,gdkmain-x11.c,gdkprivate-x11.h}:
	Automatically initialize GDK for the current locale
	on gdk_init(). Don't reset locale to C when
	XSupportsLocale() fails.

	* gdk/linux-fb/gdkim-fb.c (gdk_set_locale): Remove
	useless checks for UTF-8 locale breakage that mattered
	only for X.

	* examples/calendar/calendar.c
	tests/{testgtk.c,testtext.c,testcalendar.c}: Remove calls to
	gtk_set_locale().

	* gtk/gtkiconfactory.c gtk/gtkitemfactory.c:
	gdk_pixbuf_new_from_stream => gdk_pixbuf_new_from_inline.
