  - Fix force-stopping mirrors.
  - Introduce 'idle' functionality, which works by marking components as
    clean after the given idle time.
  - Use shutdown hooks to mark mirrors as clean after all file systems are
    unmounted.
  - Use g_topology_try_lock() in the event thread to avoid deadlocks, because
    some classes hold the topology lock when calling g_(read|write)_data().
  - Keep consumers open even if mirror is not open to avoid races which taste
    mechanism and to be able to always update metadata.
  - Treat components which has I/O errors as broken, don't try to rebuild
    them.
  - Introduce metadata backward compatibility code, which updates detected
    all metadata to the current version.
