        * gtk/gtktreeprivate.h: New arguments

        * gtk/gtktreeview.c:
        (gtk_tree_view_class_init): Add key_release callback
        (gtk_tree_view_init): Initialize timeout handler
        (gtk_tree_view_unrealize): clear timeout if needed
        (gtk_tree_view_key_press): Typeahead support
        (gtk_tree_view_key_release): Not used yet -- will be needed for
        typeahead.
        (gtk_tree_view_search_entry_flush_timeout): Remove typeahead entry
        in a timeout.
        (gtk_tree_view_ensure_interactive_directory):
        (gtk_tree_view_real_start_interactive_search):
        (gtk_tree_view_search_init):
        (gtk_tree_view_start_interactive_search): Typeahead support added.
        (gtk_tree_view_search_dialog_hide): Clear timeout and text when we
        hide.
