Threads vs. Queues lifetimes, cleanups.
...
- Ideally Queues must outlive the threads using them, but wasn't done so. Yes, std::shared_ptr them!
- Now queues are always valid in the context of the threads using them.
- No longer need tedious queues deallocation by the original owner.
- Misc cleanups.

Make ReBuffer refcount management automatic, using std::shared_ptr:
...
- No longer need to call setRefCount() / decRefCount()
- Restore old ThreadBlockingQueue using std::deque, for std::shared_ptr correct behaviour.

SpectrumVisualProcessor Zoom rework
...
- Offloads some zoom processing from liquid-dsp to FFTW
- Eliminates aliases crawling across during zoom
- Doubles internal FFT allowing some additional visual smoothing
- Reduces CPU usage while zoomed deeply
- Eliminates CPU spikes while zooming
