 src/w32.c (max_filename_mbslen): New function.
 (normalize_filename, readdir): Use it to detect locales where ANSI
 encoding of file names uses a double-byte character set (DBCS).
 If a DBCS encoding is used, advance by characters using
 CharNextExA, instead of incrementing a 'char *' pointer.  Use
 _mbslwr instead of _strlwr.
