	Make the non-_l functions wrappers around the _l functions.
	* include/monetary.h: Declare __vstrmon_l.
	* include/string.h: Add libc_hidden_proto for __strcoll_l and
	__strxfrm_l.
	* include/time.h: Define ptime_locale_status.  Declare
	__strptime_internal.
	* include/wchar.h: Add libc_hidden_proto for __wcscoll_l and
