Add abstractions for traffic generator split into those that can and
can't capture traffic.

The Scapy implementation uses an XML-RPC server for remote control. This
requires an interactive session to add Scapy funcions to the server. The
interactive session code is based on another patch [0].

The basic test case is there to showcase the Scapy implementation - it
sends just one UDP packet and verifies it on the other end.
