    mksquashfs/unsquashfs: Add filesystem flag to handle new -noId option
    
    Add new SQUASHFS_NOID flag to show when the Id table (Uids/Gids) has
    been stored uncompressed, but the main metadata tables (inode and
    directory) are stored compressed.
    
    Note both SQUASHFS_NOI and SQUASHFS_NOID should never be set in a
    filesystem as SQUASHFS_NOI implies SQUASHFS_NOID for backwards
    compatibility.
