            * gtk/gtksignal.c (gtk_signal_handler_unref): reflect the presence of
            signal connections through unsetting GTK_CONNECTED.
            (gtk_signal_handler_insert): reflect the presence of signal connections
            through setting GTK_CONNECTED.
            (gtk_signal_real_emit): only check for handler emissions if the object
            has the GTK_CONNECTED flag set.
            (gtk_signal_handler_pending): don't check for pending handlers if the
            GTK_CONNECTED flag is not set for this object.
    
            * gtk/gtkobject.h (enum): new flag GTK_CONNECTED to indicate whether
            a GtkObject has signal handler connections.
    
            * gtk/gtkobject.c (gtk_object_real_destroy): only if GTK_CONNECTED is
            set for this object call gtk_signal_handlers_destroy().
    
            * gtk/gtktypeutils.h (GTK_TYPE_IS_A): deprecated macro, since it caused
            multiple processing of macro args.
    
            * gtk/gtktypeutils.c:
            * gtk/gtkobject.c:
            * gtk/gtkwidget.c:
            * gtk/gtksignal.c: reverted GTK_TYPE_IS_A back to gtk_type_is_a.
