iso9600_stat now has filename inside it.
iso9660_fs_readdir now returns a list of iso9660_stat_t's rather than filenames. This should reduce by a small amount the number of CD reads since we store more information in the iso9660_fs_readdir return. However all of this is in preparation for greatly reducing the number of CD reads when picking out segment lsn information.
