Update.

* locale/programs/ld-collate.c (read_directions): Fix a few messages.
	(collate_finish): Test that position is used in all sections for
	a level or in none.

	* string/strxfrm.c: Optimize a bit.  We don't need the highest bit
	of the index returned by findidx.

	* string/strcoll.c: Complete rewrite for new collate implementation.
	* wcsmbs/wcscoll.c: Don't use strcoll.c, implement dummy implementation
	locally.
