AEC3: Decrease latency until the delay has been detected

Browse Source 
This CL utilizes the existing, but unused, ability to set
different histogram thresholds for early and late delay
estimation. It does so by tuning the parameters for these.

On top of that, some corrections are added to correctly
handle resets and the use of the hysteresis thresholds.
