Sync Corridor.

The current sync logic drops all old audio data at playback start to start with nearly the same audio and video pts. So the theoretical initial AV-diff is 0ms. However, the real one isn't because it takes some time from BufferingThresholdReached() to the first AV Sync. The tolerance window historically changed from -25/+55ms (original softhddevice) to -5/+35 (softhddevice-drm) up to -20/20ms, which is a symmetrical window around the theoretical 0ms-sync-destination. The AV-diff is mostly stable once synched (except for the consequences of ClockDriftCompensation) but has outliers ~3-4ms from time to time due to audio pts fluctuation. Now, if the initial sync was done to -4ms and such an outlier arrives, we land at -7ms, the frame is dropped and our new AV-diff is +14ms now. This can be avoided by the -20/+20ms window. threshold in ms, when to duplicate video frames to keep audio and video in sync
