Motivation: Capturing all packets is expensive. Recording to a ring buffer and then outputting on a triggering event allows this cost to be reduced. Modifications: Add a new handler - NIOPCAPRingCaptureHandler. This derives from the existing NIOWritePCAPHandler and generates PCAP recordings. A ring buffer contained in this handler stores the captured packets until RecordPreviousPackets is received as a user message at which point they are flushed to the sink. Result: There is a new handler capable of outputting packet captured data only in the build up to a known event.
