Jean-Pierre André 8073ab6764 Supported use of WSL special file 
The Windows Subsystem for Linux (WSL) of Windows 10 uses reparse points
to record special files (symlinks, fifos, sockets, char or block devices).
Honor such reparse points with the same meaning as WSL.

/*
* TODO LIST:
* - Better error checking. (focus on ntfs_dump_volume)
* - Comment things better.
* - More things at verbose mode.
* - Dump ACLs when security_id exists (NTFS 3+ only).
* - Clean ups.
* - Internationalization.
* - Add more Indexed Attr Types.
* - Make formatting look more like www.flatcap.org/ntfs/info
*
* Still not dumping certain attributes. Need to find the best
* way to output some of these attributes.
*
* Still need to do:
* $REPARSE_POINT/$SYMBOLIC_LINK
* $LOGGED_UTILITY_STREAM
