Chris Piazza 243b289ab1 Import of tcpflow.
Tcpflow is a tool for capturing data transmitted as part of TCP connections
(flows), and stores it in a way that is convenient for protocol
analysis or debugging.  tcpflow reconstructs the actual data streams
and stores each flow in a seperate file for later analysis.

tcpflow is a program that captures data transmitted as part of TCP
connections (flows), and stores it in a way that is convenient for
protocol analysis or debugging. A program like 'tcpdump' only shows a
summary of packets seen on the wire, but usually doesn't store the
data that's actually being transmitted. In contrast, tcpflow
reconstructs the actual data streams and stores each flow in a
separate file for later analysis.
tcpflow understands sequence numbers and will correctly reconstruct
data streams regardless of retransmissions or out-of-order delivery.
However, it currently does not understand IP fragments; flows
containing IP fragments will not be recorded properly.
Note: this port includes a small patch that adds the capability of
reading the packets from a tcpdump(1) capture file, using
a new option (-r).
