For XEMBED embedding add a _XEMBED_INFO property to the client with

Mon Jul  2 16:53:25 2001  Owen Taylor  <otaylor@redhat.com>

	* gtk/xembed.h gtk/gtkplug.c gtk/gtksocket.c: For
	XEMBED embedding add a _XEMBED_INFO property to the
	client with version number and a "mapped" flags.
	Use the mapped flag instead of the racy MapRequestEvent

        * gtk/gtksocket.c: Clean up the gtk_socket_steal()
	code to reliably set things (when the child is a passive
	embedder participating in the XEMBED protocol) intead
	of just being a hack for embedding non-participating
	programs. Fix various bugs and race conditions.

	* gtk/gtksocket.[ch] gtk/gtkplug.[ch]: Make local embedding
	work by simply making the GtkSocket the gtk parent
	of the GtkPlug. Set a flag in this case and make
	the GtkPlug work like a normal container by overriding
	methods such as check_resize and "chaining past" GtkWindow
	to GtkBin.

 	* gtk/gtkentry.c (gtk_entry_real_activate)
	  gtk/gtkmain.c (gtk_propagate_event):
 	Eliminate use of gtk_widget_get_ancestor (widget, GTK_TYPE_WINDOW).

	* gtk/gtkwidget.c (gtk_widget_get_toplevel,
	gtk_widget_get_ancestor):
	Explain	why gtk_widget_get_ancestor (widget, GTK_TYPE_WINDOW)
	might not give the expected result and recommend
	an alternative.

	* tests/testsocket.c tests/testsocket_child.c
	tests/testsocket_common.c tests/Makefile.am: Extended
	to test different type of adding plugs to sockets
	(local,active,passive),	and to test mapping/unmapping
	the plug.

 	* gdk/gdkwindow.c (_gdk_window_destroy_hierarchy): Don't
 	mark the window as destroyed until after we
 	called _gdk_windowing_window_destroy().
	(_gdk_windowing_window_destroy() may use GDK functions
	on the window.)

 	* gdk/x11/gdkinput.c: Remove the check for finalization -
 	devices can be finalized under some circumnstances.

 	* gdk/x11/gdkinput-x11.c (gdk_input_device_new): Fix
 	small problem with GDK_TYPE_DEVICE.
