List mounted btrfs disks with subvolid

Browse Source 
When listing mounted devices, list the subvolid of the mountpoint, since
a single btrfs disk can be mounted multiple times using subvolumes.
Additionally tag snapshots with subvolid to keep track of this. This
will break current usage, but users can manually tag old snapshots with
subvolid's in order to migrate them. Add -s/--subvolid command line
parameter to pass specified subvolid to program.

Cf. #45.
