A user provided a SMB2 pcap with the reserved1 field of a ReadResponse
set to 1 instead of 0. This confused the padding computation due to
including this byte into the offset. Properly split data_offset and
reserved1 into individual byte fields.
Closes#4730
connection_state_remove() is invoked after Done(), so it's not a good
idea to remove the tap analyzers before in case they have up-to-date
information for the connection val.

Writing a test, the packet was tapped after protocol analysis at least
for TCP. Ensure tapping happens before. The adapter->Process() moving
after pkt->session made me a bit wondering if things are underspecified
here, but seems reasonable to set the session on pkt before adapter->Process().

Now that SessionAdapter implements UpdateConnVal(), the individual
adapters need to call that instead of Analyzer::UpdateConnVal()
Thanks clang-tidy.

This commit introduces a mechanism to attach light weight analyzers to
the root analyzer of sessions in order to tap into the packets delivered
to child analyzer.
* origin/topic/awelzel/defer-more-stuff:
RecordType: Ensure &default fields are always re-initialized
Attr: Deprecate using &default and &optional together on record fields
RecordType: Allow deferring &default=vector(), set(), table() fields
The conn protocol scripts now assume that new_connection is run before
connection_state_remove. Update the DNS analyzer to raise the
new_connection event.
This class is a parameter of virtual methods of the Backend API for users
to implement and also a parameter to the HookPublishEvent() API. Seems it
shouldn't be in detail and instead we should own it.
Alternatively, could mark the cluster APIs as not-stable-yet, but I
think we can move forward and make it non-detail for 8.0.
* origin/topic/awelzel/4431-zeromq-drop-policy-v2:
cluster.bif: Improve Cluster::publish() docstring
btest/cluster/zeromq: Add tests for overload behavior
cluster/zeromq: Metric for msg errors
cluster/zeromq: Drop events when overloaded
cluster/zeromq: Comments and move lookups to InitPostScript()
cluster/zeromq: Rework lambdas to member functions
cluster/zeromq: Support local XPUB/XSUB hwm and buf configurability
cluster/OnLoop: Support DontBlock and Force flags for queueing
cluster/ThreadedBackend: Injectable OnLoopProcess instance
When either the XPUB socket's hwm is reached, or the onloop queue is
full, drop the events. Users can set ths xpub_sndhwm and
onloop_queue_hwm to 0 to avoid these drops at the risk of unbounded
memory growth.
