RegisterReceivedPacketCallback is used instead of sigslot::SignalReadPacket. The callback use a new data class ReceivedPacket that combine meta data and packet payload from a received packet. This is the first step in an attempt to cleanup the data types used in the packet receive pipeline. Eventually, the ReceivedPacket class can contain more meta data such as ECN information.
