Removed KFileDiskDevice functionality for now (since it would have required more changes). Also disabled actual partition publishing/unpublishing, because this will be done differently. This change will temporarily break the DiskDeviceManagerTest build. git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7914 a95241bf-73f2-0310-859d-f6bbb57e9c96
