Title: OpLabelVolume optimization

- a volume with singleton z axis (aka 'image') is now given to `vigra.analysis.labelImageWithBackground` (improves speed)
- locking is done on thread level instead of on request level (removed potential deadlock with overlapping requests)
- the operator is using really abstract classes
- writing an implementation for lazy CC labeling should be easier now
