fbb374d8ed Add a reliability term to the echo detector. 
This will ensure that the estimated likelihood starts at a low value and prevents initial spikes.

af27ed01d7 Add algorithm for Residual Echo Detector. 
This algorithm calculates an estimate of the Pearson product-moment correlation coefficient between the power of 10ms audio buffers taken from the render and capture sides, for various different delay values.

9f4a4a096b Add empty residual echo detector. 
This CL does not contain the actual algorithm, but only creates an empty processing component and connects the right signals to it. The algorithm will be added in a follow-up CL.
