remove unnecessary TRACKMODELCAP
Minor lint.
Allow a ControlObjectThread to be initialized with a ConfigKey alone. This eliminates the verbose pattern of ControlObjectThread(ControlObject::getControl(...)).
Pull potmeter-adjuster conrols out of ControlPotmeter itself and into a utility class.
Add TwoWayMessagePipe, a wrapper around FIFO<T> that lets you have a two way non-blocking message pipe.
Eliminate EngineControl seek/seekAbs signals in favor of direct calls.
Get rid of gratuitous signal usage in EngineWorkerScheduler. Also get rid of QSet to track active workers (eliminates the need for locking).
Workaround thread issue where the scaling engine could get called by the GUI thread.
This will be obsolete when engine-control-refactor is merged.
