	Merged from gtk-2-4:

	Fixes #155744:

	Try to load the whole file system model within a specified time.

	* gtk/gtkfilechooserdefault.c (set_list_model): Don't create and
	set the sort model here.  Instead, set up a timer in which we'll
	try to load the file system model.
	(load_set_model): Create and set the sort model here.
	(load_setup_timer): New function to set up a timer and switch to
	the LOAD_LOADING state.
	(load_remove_timer): New function to unset the timer and switch to
	the LOAD_FINISHED state.
	(browse_files_model_finished_loading_cb): Remove the timer if
	needed and set the file system and sort model; switch to the
	LOAD_FINISHED state.
	(gtk_file_chooser_default_finalize): Remove the load timer.
	(gtk_file_chooser_default_init): Start in the LOAD_FINISHED state.
