Fix vamp-plugins SConscript to add the INTERNAL_VAMP_PATH to the include path correctly.
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.
Don't crash if user has a keyboard key configured for a control that doesn't exist
Fix vinyl input toggling not working correctly
Change EngineWorker so that EngineWorkerScheduler marks jobs as active and the EngineWorker marks itself as inactive. Should fix race-condition related to reading on slower hardware.
Use QAtomicInt and atomic primitives for testing if a seek is queued. This prevents memory write re-orderings that could lead us to seeking to an invalid location. Use alignment attributes for m_dQueuedPosition to make sure it is 8-byte aligned.

0-length reads are no longer a problem for RAMAN. Remove the early-exit so that a 0-length read (i.e. maybe a read failed or maybe we are past a loop triggerboundary) will end up hitting the logic that takes the loop.
Use LoopingControl::process to determine whether to take a loop in ReadAheadManager instead of copying the logic (incorrectly).
Get rid of seeking based on the result of EngineControl::process at the end of EngineBuffer::process. This is fully taken care of by the RAMAN now.
Delete unused variable.
Create EngineBufferScaleDummy.
Fix issue in EngineBufferScaleLinear that can cause loops to go out of sync. Fixes Bug #1025007.

* Prepended samples from pre-existing buffer were not represented as part of read-sample count.
* RAMAN was not called multiple times so reads across loop boundaries will only get the pre-loop samples.
* Samples not read were not zero'd.
* m_fPrevSample assignment ignored pre-existing buffer samples that were copied.
