Motivation:
It's useful to know the overhead we could be adding by including
the PCAP handler.
Modifications:
Add a new executable based on the NIO performance testing executable.
Result:
There is a new executable which runs a short test of sending and receiving
data through the HTTP/1 handler using multiple eventloops and showing
three options.
1) Vanilla
2) With in memory PCAP never written to disk
3) With a disk based PCAP.
