History
Per Åhgren e4db6a1518 AEC3: Improved the accuracy of the adaptive filter 
This CL adds a functionality that jump-starts the
AEC3 shadow filter whenever it performs consistently
worse than the main filter.
The jump-start is done such that the shadow filter
is re-initialized using the main filter coefficients.

The effects of this is a significantly more accurate
main linear filter which leads to less echo leakage
and better transparency
