	Fix major bug in row ref handling, so the new combo box
	will actually work right (:. Bug #107748. Patch written
	with help from Tim Janik.

	The basic idea is to update the row refs in a closure,
	before the actual signal is emitted (rather than having
	the model connect signal handlers).

	* gtk/gtktreemodel.c (gtk_tree_model_base_init): change
	g_signal_new calls for row_inserted, row_deleted and
	rows_reordered to use the new marshallers,
	(row_inserted_marshall), (row_deleted_marshall),
	(rows_reordered_marshall): the new marshallers,
	(gtk_tree_row_ref_inserted_callback): renamed to
	gtk_tree_row_ref_inserted since it isn't a callback
	anymore and gets called by the marshaller now,
	(gtk_tree_row_ref_deleted_callback): likewise,
	(gtk_tree_row_ref_reordered_callback): likewise,
	(connect_ref_callbacks), (disconnect_ref_callbacks):
	removed,
	(gtk_tree_row_reference_new_proxy),
	(gtk_tree_row_reference_free),
	(gtk_tree_row_reference_inserted),
	(gtk_tree_row_reference_deleted),
	(gtk_tree_row_reference_reordered): updated.
