To more easily determine if for example the AEC is not working properly one could monitor how often the estimated delay is out of bounds. With out of bounds we mean either being negative or too large, where both cases will break the AEC. A new delay metric is added telling the user how often poor delay values were estimated. This is measured in percentage since last time the metrics were calculated. All APIs have been updated with a third parameter with EchoCancellation::GetDelayMetrics() giving the option to exclude the new metric not to break existing code. The new metric has been added to audio_processing_unittests with an additional protobuf member, and reference files accordingly updated. voe_auto_test has not been updated to display the new metric.
