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 with verbose level 4
Seq# Time Port:Que Description
1 0.000000000 0:0 :: → ff02::16 ICMP 143
2 0.000000000 0:0 :: → ff02::1:ff98:2b46 ICMP 135
36 0.512762002 0:0 fe80::285f:1fff:fe98:2b46 → ff02::fb UDP 120 5353 → 5353
37 0.512779925 0:0 fe80::285f:1fff:fe98:2b46 → ff02::fb UDP 120 5353 → 5353
v3 - use a string buffer instead of use stdio stream
because that can get garbled when dealing with multiple threads.
- don't use longjmp unwind, as it can lead to bugs later.

net: add new packet dissector
test: add test for packet dissector
test-pmd: add more packet verbose decode options
