	* gtk/gtkwindow.c (gtk_window_activate_focus): Don't ignore the
	return value of gtk_widget_activate().
	(gtk_window_activate_default): Likewise.  Fixes #137008.

	* gtk/gtkfilechooserdialog.c (response_cb): Act on positive
	response IDs we recognize, rather than bailing out on cancellation
	ones.  Fixes #136237; patch by Olivier Andrieu
	<oliv__a@users.sourceforge.net>.
	(file_chooser_widget_file_activated): If the dialog doesn't have a
	default widget, try to find a suitable response widget on our own.
	People should *really* be using gtk_dialog_set_default_response(),
	but this is to help lazy programmers.

	* gtk/gtkdialog.c (_gtk_dialog_get_response_for_widget): New
	internal function.
	(get_response_data): Add a "create" argument so that we don't
	unconditionally create the response data.
