Denny a302d098de 126 - Significant improvement in processor and memory utilization. Refactors all USB tuner sample processing with a new USBTransferProcessor class. LibUSB transfer timeout processing is now consolidated under the TunerManager and tuners register with this singleton to auto-start or auto-stop USB bulk transfer processing. Resolves long-standing issue impacting multi-tuner use where the second and subsequent tuners may have been routinely starved for LibUSB processing time under heavy-loading. All tuner buffer threaded processing is now handled as runnables in the scheduled thread pool, eliminating tuner-dedicated processing threads. Added tuner buffer size management to prevent memory blow-out when down-stream processing is either lagging or impacted by java garbage collection operations. Both tuners and individual DDC channels now have bounded sample buffer queues that automatically enter and exit overflow mode when predefined max/reset thresholds are met. When any queue goes into overflow mode, sample buffers are simply dropped in favor of preserving program/memory stability.
