Fix #399071, suggestion from Benoit Dejean.

2007-06-05  Kristian Rietveld  <kris@gtk.org>

	Fix #399071, suggestion from Benoit Dejean.

	* gtk/gtkliststore.[ch] (gtk_list_store_set_vector_internal): new
	function, factored out code iterating (columns, values) vectors from
	gtk_list_store_new_with_valuesv to here,
	(gtk_list_store_set_valuesv): new public function to set list store
	values using (columns, values) vectors,
	(gtk_list_store_new_with_valuesv): call new _set_vector_internal
	instead.

	* gtk/gtktreestore.[ch] (gtk_tree_store_set_vector_internal),
	(gtk_tree_store_set_valuesv), (gtk_tree_store_new_with_valuesv):
	likewise.

	* gtk/gtk.symbols: updated.
