free undo_un/selection, unselect list_item before disconnect signal

Fri Oct 30 20:02:36 1998  Lars Hamann  <lars@gtk.org>

	* gtk/gtklist.c (gtk_list_remove_items_internal):
	free undo_un/selection, unselect list_item before disconnect
	signal functions
	(gtk_list_destroy): removed. gtk_list_shutdown clears the list
	already
	(gtk_list_signal_item_select) (gtk_list_signal_item_deselect)
	(gtk_list_signal_item_toggle)	(gtk_list_signal_scroll_horizontal)
 	(gtk_list_signal_toggle_focus_row) (gtk_list_signal_select_all)
 	(gtk_list_signal_unselect_all) (gtk_list_signal_undo_selection)
 	(gtk_list_signal_start_selection) (gtk_list_signal_end_selection)
 	(gtk_list_signal_toggle_add_mode) (gtk_list_signal_scroll_vertical)
 	(gtk_list_signal_extend_selection) (gtk_list_signal_focus_lost):
 	new functions. These functions are signal connected to inserted
 	list_items, to handle key bindings and GtkItem::de/select/toggle
 	signals.

	* gtk/gtklistitem.c (gtk_list_item_class_init): added missing
	gtk_object_class_add_signals call.
	(gtk_list_item_toggle_focus_row) (gtk_list_item_select_all)
	(gtk_list_item_unselect_all) (gtk_list_item_undo_selection)
	(gtk_list_item_start_selection) (gtk_list_item_end_selection)
	(gtk_list_item_extend_selection) (gtk_list_item_scroll_horizontal)
	(gtk_list_item_scroll_vertical) (gtk_list_item_toggle_add_mode):
 	removed. These functions are handled via connected
 	gtk_list_signal_* functions now
