constraint: Re-implement using update_allocation()

Browse Source 
Instead of using the fixed position and size API, use the newly added
update_allocation() virtual function in ClutterConstraint to change the
allocation of a ClutterActor. This allows using constraints inside
layout managers, and also allows Constraints to react to changes in the
size of an actor without causing relayout cycles.
