Measures the duration of each packet loss concealment (a.k.a. expand) event that is not followed by a merge operation. Having decoded and played packet m−1, the next expected packet is m. If packet m arrives after some time of packet loss concealment, we have a delayed packet outage event. However, if instead packet n>m arrives, we have a lost packet outage event. In NetEq, the two outage types results in different operations. Both types start with expand operations to generate audio to play while the buffer is empty. When a lost packet outage happens, the expand operation(s) are followed by one merge operation. For delayed packet outages, merge is not done, and the expand operations are immediately followed by normal operations. This change also includes unit tests for the new statistics.
