* 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/gtktable.c:
* gtk/gtktogglebutton.c:

* gtk/gtkpacker.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.
