[PATCH v8 0/7] Test-pmd packet decode enhancements

[Stephen Hemminger]

While debugging TAP rte_flow discovered that test pmd verbose output
was confusing and unhelpful. Instead, made a simple dissector that
prints one line per packet like this in test-pmd.

The new commands are:
	testpmd> set output /tmp/packet.log
	testpmd> set format dissect

To enable packet logging need to use:
	testpmd> set verbose 3

v8 - added JSON output format, and ability to redirect packet log,
     and don't overload verbose option.

v7 - change rte_dissect to return number of characters that would
     be printed (same as snprintf). And tests around that.

v6 - validate result of rte_dissect for simple packet

v5 - breakout the additional ICMP types into header
   - fix some decoding bugs in ARP and ICMP
