RTP packets can be padded with extra data at the end of the payload. The usable payload length of the packet should then be reduced with the padding length, since the padding must be discarded. This was not the case; instead, the entire payload, including padding data, was forwarded to the audio channel and in the end to the decoder. A special case of padding is packets which are empty except for the padding. That is, they carry no usable payload. These packets are sometimes used for probing the network and were discarded in RTPReceiverAudio::ParseAudioCodecSpecific. The result is that NetEq never sees those empty packets, just the holes in the sequence number series; this can throw off the target buffer calculations. With this change, the empty (after removing the padding) packets are let through, all the way down to NetEq, to a new method called NetEq::InsertEmptyPacket. This method notifies the DelayManager that an empty packet was received.
