Adding dependency tracking to constraint satisfaction
The previous scheme checked all constraint bounds twice everytime
the bounds for a parameter in a constraint were changed. The new scheme,
which can be disabled by unsetting `Config.trackContrDeps`, only
checks those cbounds that directly or indirectly mention the changed
parameter.
