Implement per-locale string functions

strcasecmp_l, strcoll_l, strncasecmp_l, strxfrm_l,
wcscasecmp_l, wcscoll_l, wcstrncasecmp_l, wcstrxfrm_l,
strftime_l.

Add missing CHEWOUT_FILES from previous patch.

TODO: strfmon_l.

+INDEX
+	strcasecmp_l
+
+ANSI_SYNOPSIS
+	#include <strings.h>
+	int strcasecmp_l(const char *<[a]>, const char *<[b]>,
+			 locale_t <[locale]>);
+
+DESCRIPTION
+	<<strcasecmp_l>> compares the string at <[a]> to
+	the string at <[b]> in a case-insensitive manner.
+
+	if <[locale]> is LC_GLOBAL_LOCALE or not a valid locale object, the
+	behaviour is undefined.
+
+RETURNS 
+
+	If <<*<[a]>>> sorts lexicographically after <<*<[b]>>> (after
+	both are converted to lowercase), <<strcasecmp_l>> returns a
+	number greater than zero.  If the two strings match,
+	<<strcasecmp_l>> returns zero.  If <<*<[a]>>> sorts
+	lexicographically before <<*<[b]>>>, <<strcasecmp_l>> returns a
+	number less than zero.
+
+PORTABILITY
+<<strcasecmp_l>> is POSIX-1.2008.
+
+<<strcasecmp_l>> requires no supporting OS subroutines. It uses
+tolower_l() from elsewhere in this library.
