Changes:
Patch 2:
  * Fixed unmount warnings to refer to the right $src vs $dest variable.

Patch 4 is new.

Patch 5 (previous 4):
  * Instead of refusing moves when any snapshots exist, use the new
    'is_volume_in_use' variant to check whether the volume is actually
    used in a snapshot, in which case we simply don't allow the --delete
    parameter.
  * Don't use both 'disk' and 'volume' in the parameter descriptions.
  * - Let the config key be referred to as $mpkey instead of $volume,
    - its parsed data s $mpdata
    - the actual storage volumes only as $old_volid and $new_volid
    instead of mixing $mp, $mp->{volume}, $volume, etc. in confusing
    ways.


I tested a bit around with LVM-thin, ZFS, NFS as backing storage.
I did not run into anything problematic yet.
The code looks OK to me, but I'm not to much into this topic for
a real in-depth review so I may have missed something.

Wolfgang Bumiller (5):
   factor out disk allocation+formatting for reuse
   implement copy_volume
   use copy_volume for full clones
   config: is_volume_in_use: ability to search only snapshots
   add move_volume api call
