* Adapt lfs_cleanerd to use the fcntl call to get the Ifile filehandle, so it need not be in the namespace. * Make lfs_cleanerd be more careful when there are very few available segments. * Remove the Ifile from the filesystem namespace. The cleaner now uses a fcntl call on the root inode to find the Ifile filehandle. * Make lfs_cleanerd less verbose when the filesystem is unmounted.
