Log:
2008-05-28  Kristian Rietveld  <kris imendio com>

	Refactor expand/collapse timeout handling (amendment to bug 511217).

	* gtk/gtktreeview.c (add_expand_collapse_timeout),
	(remove_expand_collapse_timeout): new functions, the remove function
	also clears expanded_collapsed_node,
	(cancel_arrow_animation): moved to be next to the add/remove timeout
	functions,
	(gtk_tree_view_unrealize),
	(gtk_tree_view_row_deleted),
	(gtk_tree_view_set_model),
	(cancel_arrow_animation),
	(gtk_tree_view_real_expand_row),
	(gtk_tree_view_real_collapse_row): use the new add/remove functions.
