* 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.
