Gustaf Ullberg a99b89b41c AEC3: Echo remover handles multiple capture signals. 
Echo remover processes all microphone signals. Suppression gains are
computed separately for each capture signal. The minimum gains determine
the final suppression gains applied.

Only the first channel is synthesized. A follow-up CL will add the
synthesis of the remaining channels.
