Emulated volumes above private volumes.

When a private volume is mounted, create an emulated volume above it
hosted at the /media path on that device.  That emulated volume is
automatically torn down when unmounting the private volume.

Add "removed" state for volume, which signals to framework that
media has left the building, send when the volume is destroyed.
