d90b566b08 GeneratePlacePose: Remove property "ik_frame" from stage

- Allow subframes to be used as "object" frames

4cc1f567d6 FallbacksPrivateConnect
Implement Fallbacks behavior for children of type Connecting.
All other connect-like children are currently infeasible to handle,
because we cannot forward a single job, i.e. a pair (from, to)
to the next child, but only individual states.
However, passing states, will cause creation of undesired state pairs
as jobs in subsequent children.

7237e81547 Rework FallbacksPrivate*
Further factorize and simplify FallbacksPrivate classes employing ideas from @v4hn.
The key difference between the variants his how they advance to the next job.
Thus, the only virtual method required is nextJob().

a31e52dd53 Propagate status across Connecting gap
Not only propagate updates along solution paths, but also bridge
the gap of a `Connecting` stage.

- If a state becomes enabled, re-enable opposite `ARMED` states as well.
- If a state becomes pruned, also prune opposite states if they don't have alternatives.
- Make sure that we don't run into a recursive update loop by disabling notify() callbacks.

06ae5ddf9c Fix hasPendingOpposites()
- Switch directions: FORWARD <-> BACKWARD to make the function reusable for status propagation.
- We need to ignore the source state when looking for opposite states of the target state.
  Thus add both, source and target state arguments.

29d1e44c5d Rework updatePriority() functions
- Centrally distinguish between have owner() or not in InterfaceState::updatePriority()
- Have a separate updateStatus() method to just update the pruning status
- Split Interface::updatePriority() into a method taking the InterfaceState*
  and one taking an Interface::iterator (for efficiency)
- Early return in container.cpp's updateStatePrios()

9a583ab006 run only one compute step per call
Note that while this ensures other stages outside the Fallbacks container
can compute as well, it does not solve the problem internally.
A new incoming state will only ever be considered once
the current stage cannot compute any more.

We have no way of telling a child to compute for *a specific state* for now.
So once we copied a state to its interface we have to let it compute until
all possibilities are exhausted to detect whether or not it could generate a solution for it.
If we wouldn't do so, there were no way of knowing when to fall back
to the next child as long as the stage can still compute on *any* copied solution.
