Merge of Echo canceller 3 improvements for setups with headsets.

This is a merge of the CL https://codereview.webrtc.org/2823903003
into M59.

This CL improves the echo cancellation performance on setups where
headsets are used (systems with such low echo path gain
that no correlation between the render and capture signals
can be found) in 4 ways:
1) The echo path gain for systems with headsets is assumed to be
nonzero.
2) The stationary component of the render power is not included
in nonlinear echo power estimate.
3) The behavior after echo path gain changes is made less cautious.
4) The detection of systems with headsets is made more rapid.

CLs for remote refs other than refs/heads/master must contain NOTRY=true and
NOPRESUBMIT=true in order for the CQ to process them
