	Implement lazy extended input initialization on Win32, by Robert
	Ögren. Fixes #163163, possibly #162334. Lazy initialization would
	be a good idea in any case even if it didn't fix any visible
	problems, though.

	The Wacom tablet driver seems to get confused if Wintab is
	initialized but no window is shown before the process exits. This
	is the case for some GIMP plug-ins, for instance.

	* gdk/win32/gdkinput-win32.c (_gdk_input_wintab_init_check): Made
	non-static (and renamed).
	(_gdk_input_init): Don't call _gdk_input_wintab_init_check().

	* gdk/win32/gdkinput-win32.h: Declare _gdk_input_wintab_init_check().

	* gdk/win32/gdkinput.c (gdk_devices_list,
	gdk_display_list_devices, gdk_input_set_extension_events): Call
	_gdk_input_wintab_init_check() here instead.
