Inform the AEC3 echo remover about the status of the estimated delay

Browse Source 
This CL adds functionality for passing the information about the
estimated delay to the echo remover in AEC3.
The CL also adds information about how long ago the delay changed,
and how long ago the delay estimate was updated.
