Gustaf Ullberg 83b00f020e AEC3: Computation of comfort noise gains from suppression gains 
This change corrects the computation of the comfort noise gains.

Previously the comfort noise gain of band k, CG_k, was computed
from suppression gain of band k, SG_k, as:
CG_k = 1 - SG_k

But since the two signals are uncorrelated (the comfort noise
is randomly generated), the correct gain to maintain power is:
CG_k = sqrt(1 - SG_k^2).
