* configure.in: Require at least libxml 2.4.7, since that's the version where xmlFree and friends were moved out of <libxml/xmlmemory.h>. * components/news/nautilus-news.c: * components/text/nautilus-text-view.c: * libnautilus-private/nautilus-customization-data.c: * libnautilus-private/nautilus-directory-async.c: * libnautilus-private/nautilus-find-icon-image.c: * libnautilus-private/nautilus-link-desktop-file.c: * libnautilus-private/nautilus-link-historical.c: * libnautilus-private/nautilus-link.c: * libnautilus-private/nautilus-metafile.c: * libnautilus-private/nautilus-theme.c: * libnautilus-private/nautilus-volume-monitor.c: * src/nautilus-bookmark-list.c: * src/nautilus-property-browser.c: * src/nautilus-window-menus.c: Remove unneeded include of <libxml/xmlmemory.h>. * components/tree/nautilus-tree-model.c: (get_node_uri): New, used only for logging ref. counts. (decrement_ref_count): New. (abandon_node_ref_count): New. (abandon_dummy_row_ref_count): New. (report_dummy_row_inserted): Do nothing if the parent is not yet in the inserted state. (report_dummy_row_deleted): Make it abandon any lingering ref count that's still in the dummy row. (report_node_inserted): Make it report that the dummy node is inserted if the node starts with a dummy child. Also, set the new inserted state so we know this node is live. (report_node_contents_changed): Do nothing if the node is not yet in the inserted state. (report_node_has_child_toggled): Do nothing if the node is not yet in the inserted state. (report_dummy_row_contents_changed): Do nothing if the parent is not yet in the inserted state. (stop_monitoring_directory): Set done_loading to FALSE so we'll get a dummy node for directories we are not monitoring. (destroy_node_without_reporting): Abandon any ref count left in the node. Also set the inserted state to FALSE before destroying children. (destroy_node): Report if the parent gains a dummy node as a result of destroying this node. (update_node_without_reporting): Don't clear done_loading any more, since stop_monitoring_directory does it now. (reparent_node): Abandon any ref count that's still in the node before reparenting it. (schedule_destroy_unneeded_children): New. (last_child_unref): Use new schedule_destroy_unneeded_children function so we cna share code with the new abandon ref count functions. (nautilus_tree_model_ref_node), (nautilus_tree_model_unref_node): Add some logging for debugging purposes. * components/tree/nautilus-tree-view.c: (compare_rows): Sort function to use when GtkTreeModelSort works. (create_tree): Hook up sort function.
