Tim Janik e63d08e43f call the base class init fucntions from all parent types upon class
Sun Jun 28 04:29:10 1998  Tim Janik  <timj@gtk.org>

	* gtk/gtktypeutils.c (gtk_type_class_init): call the base class init
	fucntions from all parent types upon class initialization.

	* gtk/gtkcontainer.c:
 	(gtk_container_get_type): announce gtk_container_base_class_init to
 	the type system.
	(gtk_container_base_class_init): new function to feature base class
	initialization.
	(gtk_container_get_child_arg):
	(gtk_container_set_child_arg): call the GtkContainerClass get_child_arg
	and set_child_arg methods of the class indicated through the argument
	name.

	* gtk/gtkobject.c:
	(gtk_object_base_class_init): new function to feature base class
 	initialization.
	(gtk_object_init_type): announce gtk_object_base_class_init to the type
	system.
	(gtk_object_class_init): setup the get_arg and set_arg pointers for
	GtkObjectClass.
	(gtk_object_setv):
 	(gtk_object_getv): call the GtkObjectClass get_arg and set_arg methods,
 	instead of bothering the type system with this.

	* gtk/gtkaccellabel.c:
	* gtk/gtkbutton.c:
	* gtk/gtkradiobutton.c:

	* gtk/gtkwidget.c:
	* gtk/gtkwindow.c:
	* gtk/gtkframe.c:
	* gtk/gtkmisc.c:
	* gtk/gtklabel.c: set the object_class->{g|s}et_arg pointers to the
	corresponding gtk_*_{g|s]et_arg functions and updated the gtk_*_get_type
	functions wrt GtkTypeInfo initialization. changed a lot of the set/get
	arg functions to take a GtkObject argument.
