Small warning cleanups.

        * gtk/gtkobject.c gtk/gtklist.c gtk/gtkplug.c gtk/gtksocket.c
        gtk/gtktreemodelsort.c gtk/gtktreeview.c: Small warning cleanups.

        * gtk/gtkradiomenuitem.c (gtk_radio_menu_item_get_group): Change
        the function definition so we don't accidentally rely on
        the compat #define from gtk_radio_menu_item_group.
        (#60782, Jeff Franks)
