Log:
MFC:
- 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.
