* remove unused bool return value from sentPacketHandler.getPTOTimeAndSpace * ackhandler: implement timer logic for path probing packets Path probe packets are treated differently from regular packets: The new path might have a vastly different RTT than the original path. Path probe packets are declared lost 1s after they are sent. This value can be reduced, once implement proper retransmission logic for lost path probes. * ackhandler: declare path probes lost on OnLossDetectionTimeout
