Log Message:
Import wcsnlen(3) to libc

The wcsnlen(3) function conforms to POSIX.1-2008 and is an addition to the
ISO C standard.

size_t wcsnlen(const wchar_t *s, size_t maxlen);

The wcsnlen(3) function computes the number of wide-characters in a wide-
-string to which s points, not including NULL terminating wide-character
code and checking no more than maxlen wide-characters. This function never
examines wide-characters beyond a wide-string of maxlen size.

This function is a safer version of wcslen(3):

size_t wcslen(const wchar_t *s);

Update STANDARDS section of wmemchr(3) describing wide-character functions.
