	* gtk/gtklabel.c gtk/gtkmenubar.c gtk/gtktreeviewcolumn.c
	  gtk/gtkwidget.c:
	Check GTK_WIDGET_TOPLEVEL(gtk_widget_get_toplevel (widget)),
	not GTK_WIDGET_GET_ANCESTOR ... see
	http://mail.gnome.org/archives/gtk-devel-list/2001-July/msg00072.html.
	Indicate the best practice in the docs for gtk_widget_get_toplevel().

	* gtk/gtkwidget.[ch]: Expose a private _gtk_widget_hierarchy_changed(),
	so GtkPlug can give the correct signals when transforming
	from a child to a toplevel.

	* gtk/gtkdnd.c (gtk_drag_dest_hierarchy_changed): Handle
	reparentation correctly.

	* gtk/gtkwidget.c (gtk_widget_propagate_hierarchy_changed):
	Propagate the previous_toplevel argument down properly.

	* gtk/gtklabel.c (gtk_label_finalize): Fix unrefing
	of wrong atr list.

	* gtk/gtkplug.[ch]: Add an "embedded" signal.

	* gtk/gtksocket.[ch]: Add "child_added", "child_removed"
	signals.

	* gtk/gtkplug.[ch] gtk/gtksocket.[ch]: Add
	functions gtk_plug_get_id(), gtk_socket_get_id(),
	to avoid the user having to worry about realization,
	and gdkx.h.

	* tests/testsocket.c: Extend to try out the new signals
	and gtk_plug/socket_get_id().

	* gtk/gtklabel.c (gtk_label_set_pattern_internal): Fix
	setting of underline attributes.

	* gdk/x11/gdkevents-x11.c (gdk_event_translate): Ignore
	DestroyNotify events from SubstructureNotifyMask

	* gdk/x11/gdkwindow-x11.c (gdk_window_reparent):
	Switch GDK_WINDOW_TYPE (window) as needed.

	* gdk/x11/gdkwindow-x11.c (gdk_window_new): Clean up,
	allow creation of toplevel windows as children of
	foreign windows.

	* gtk/gtkplug.c: Remove hacks involving changing private
	fields of GdkWindow.

	* gtk/gtkplug.[ch] gtk/gtksocket.c: Work to make
	exactly the same signals and notification
	be emitted for local embedding as for inter-process
	embedding.
