Gustaf Ullberg 040f87f934 AEC3: Allow a more stable filter during double-talk 
This is a new attempt to reduce the filter divergence
during double-talk without regressing in clock-drift
scenarios.

- The error_floor in decreased to allow for slow adaptation
  when the filter performs well.
- The leakage_diverged is increased to allow for fast adaptation
  when the shadow filter performs better.
- A new parameter, error_ceil, was added to stop the filter from
  adapting too fast.
