    	* gtk/gtkwidget.c (gtk_widget_set_parent): Enforce
    	the widget/child realization/mapping invariants.
    	* gtk/gtkwidget.[ch] gtk/gtkprivate.h: Add functions
    	gtk_widget_[get/set]_child_visible() to control
    	whether visible children of a mapped window are
    	* docs/widget_system.txt: Updated for changes in
    	container contract, and addition of GTK_CHILD_VISIBLE.
    	* gtk/gtkcontainer.c: Add generic map()/unmap()
    	functions that work for almost all containers.
    	* gtk/gtknotebook.c gtk/gtkpacker.c: Use
    	gtk_widget_set_child_visible() where necessary.
    	* gtk/*.c: Remove excess map(), unmap(), and
    	realization/mapping invariant enforcing code
    	from many containers.
