Move notification of "has_default" to here, so it is safe to call

	* gtk/gtkwindow.c (gtk_window_set_default): Move
	notification of "has_default" to here, so it
	is safe to call gtk_window_set_default() instead
	of gtk_widget_grab_default().

	* gtk/gtkwindow.c (gtk_window_set_focus): Make it call
	gtk_widget_grab_focus(), which then calls
	_gtk_widget_internal_set_focus(). This makes
	gtk_window_set_focus() a safe way of both setting
	and unsetting the focus widget.

	* gtk/gtkwidget.c (gtk_widget_propagate_state): Use
	gtk_widget_get_toplevel(), instead of gtk_widget_ancestor
	to find the toplevel.

	* gtk/gtkwindow.h: Move gtk_window_set_focus/default
	from the "internal functions" section.
