30d0b21ecc Merge remote-tracking branch 'origin/topic/dev/print-to-log'
Adjustments during merge:

- kept the UNKNOWN Log::ID as placeholder value
- changed the coverage.find-bro-logs test to check for arbitrary $path
  field values instead of just string literals
- don't force EnumVal to unsigned integer since the relevant union member
  is the signed integer and added the relevant enum values/types to
  .bif files for easier access
- compare FILE* versus file name to check for stdout equality (don't
  think it matters much, just a bit more efficient)
- minor whitespace/style tweaks

* origin/topic/dev/print-to-log:
  Added a non boolean configuration and other changes as suggested by Jon
  Allow Print Statements to be redirected to a Log# This is a combination of 3 commits.

31f60853c9 GH-646: add new "successful_connection_remove" event
And switch Zeek's base scripts over to using it in place of
"connection_state_remove".  The difference between the two is
that "connection_state_remove" is raised for all events while
"successful_connection_remove" excludes TCP connections that were never
established (just SYN packets).  There can be performance benefits
to this change for some use-cases.

There's also a new event called ``connection_successful`` and a new
``connection`` record field named "successful" to help indicate this new
property of connections.

29f386e388 Implement minimal supervised cluster configuration
More aspects of the cluster configuration to get fleshed out later,
but a basic cluster like one would use for a live deployment
can now be instantiated and run under supervision.  The new
clusterized-pcap-processing supervisor mode is also not done yet.

773b39e52e Finish implementing supervisor infrastructure
The process hierarchy and all supervisor control commands are now
working (e.g. status, create, destroy, restart), but nodes are
not currently spawned with the desired configuration parameters so
they don't yet operate as real cluster nodes (e.g. worker, logger,
manager, proxy).

5901b6d33c Allow to handle late DPD matches.
If dpd_match_only_beginning is disabled, matches of protocol signatures
can be handeld using protocol_late_match. To prevent further matching in
this case, dpd_late_match_stop may be activated.

9d489cde20 Add duration thresholding to the conn-size analyzer.
Now, in addition to setting thresholds for bytes and packet, one can set
a threshold for connection duration. Note that the threshold event is
only raised once the next packet in the connection is seen.

This also fixes a small pre-existing bug, in which a bunch of warnings
were raised if someone just used the lower-level functions without going
through the higher-level scripting API.

a42b3a1d63 MQTT Analyzer heavily updated and ported from the analyzer originally by Supriya Kumar
This analyzer generates three logs to fully display what is happening over the MQTT connection.
  - mqtt_connect.log
  - mqtt_subscribe.log
  - mqtt_publish.log

At this time it only supports MQTT 3.1 and 3.1.1

The field is populated in this order of preference:

  (2) Use the server's CHADDR field
  (3) Use the client's CHADDR field

Case (3) did not exist before this patch.
