This changes the PPPoE parser so that it doesn't forward extra bytes
that might be appended after the payload. Instead, it raises a weird if
the payload size doesn't match the size indicated by the header.
This is in line with what other protocol parsers (like UDP) are doing.
Two tests needed to be updated - with this change, the traffic in
pppoe-over-qinq.pcap is now valid TLS. A new trace was introduced for
the confirmation-violation-info test.
Addresses GH-4602
This switches the DPD logic to always log analyzers that raised a
protocol confirmation.
The logic is that, once a protocol has been confirmed - and thus there
probably is log output - it does not make sense to later remove it from
the log. It does make sense to somehow flag it as failed - but that
seems like a secondary step.

only generate history threshold events for > 1 instance mention those events in NEWS
a different sort of history update
'W' for zero window implemented; logarithmic 'T'/'C'/'W' history repetitions
I reverted a change that made TCP window tracking unconditional (possibly
accepting out-of-order packets) until further verification of test suite
changes.
