This was not implemented before. It returns the current total delay (packet buffer and sync buffer) of NetEq. This is the same information that was already available in NetEqNetworkStatistics::current_buffer_size_ms, that can be obtained through NetEq::NetworkStatistics(). But, since the current delay is a key metric of NetEq, it is convenient to have it available in a simpler way. This is a re-landing of r9359, https://webrtc-codereview.appspot.com/51149004, which was reverted in r9360. The refactoring made in r9669 facilitated the relanding.
