Update.

* libio/Makefile (routines): Add fwide.
	* libio/iofwide.c (_IO_fwide): Remove locking.  This is done in
	fwide now.  Internal calls to _IO_fwide must do locking themselves
	or don't need locking.
	* libio/fwide.c: New file.

	* elf/dl-load.c (_dl_map_object): Implement handling of DF_1_NODEFLIB.
