        * gtk/gtkctree.h
        * gtk/gtkctree.c
        * gtk/testgtk.c : New typedef GtkCTreeNode, changed all GList *node
        to GtkCTreeNode *node.

        * gtk/gtklist.h : added extended selection mode and auto scrolling.
        (struct _GtkList): removed unneeded variables timer, button,
        selection_start_pos, selection_end_pos, scroll_direction, have_grab.
        Added new variables undo_selection, undo_unselection, last_focus_child,
        undo_focus_child, htimer, vtimer, anchor, drag_pos, anchor_state,
        drag_selection, add_mode.

        New functions :
        (gtk_list_extend_selection), (gtk_list_start_selection),

        * gtk/gtklist.c :

        (gtk_list_fake_toggle_row), (gtk_list_update_extended_selection),
        (gtk_list_focus_lost)

        (gtk_list_set_focus_child): modified gtk_container_set_focus_child
        function to support auto scrolling, and avoid out-of-sync errors in
        case auf GTK_SELECTION_BROWSE
        (gtk_list_focus): modified gtk_container_focus function to avoid out
        off sync errors in case auf GTK_SELECTION_EXTENDED

        * gtk/gtklistitem.h
        * gtk/gtklistitem.c :
        New signal functions for key binding support :

        (toggle_add_mode)
        (gtk_list_item_realize): added  GDK_KEY_PRESS_MASK |
        GDK_KEY_RELEASE_MASK
        (gtk_list_item_draw_focus): modify gc if parent has add_mode set.

        (gtk_combo_popup_button_press):  grab pointer for combo->list
        (gtk_combo_button_release): ungrab only if combo->popwin HAS_GRAB
        (gtk_combo_list_key_press): take care of which child HAS_GRAB
        (gtk_comb_init): don't connect combo->button with button_release_event
