* libc/stdlib/mbrtowc.c (_mbrtowc_r): Fix case where s is null
        pointer to match C99 spec.
        * libc/stdlib/mbsrtowcs.c (_mbsrtowc_r): Fix to ignore len when
        dst is NULL.  Also fix to not alter src pointer when dst is NULL
        and call _mbrtowc_r instead of _mbtowc_r.
        * libc/stdlib/wcsrtombs.c (_wcsrtombs_r): Call _wcrtomb_r instead
        of _wctomb_r.
