henrik.lundin 63d146b743 NetEq: Rectify the implementation of PacketBuffer::DiscardOldPackets
The implementation of this method did not follow the description in
the method comment. It was supposed to delete all packets in a range
[A, B], but if at least one packet in the buffer had a timestamp lower
than A, then no packets at all were discarded. This is now fixed.
