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.

37a478ae99 GH-684: Fix parsing of RPC calls with non-AUTH_UNIX flavors
The parsing logic that should be specific to the AUTH_UNIX credential
flavor was previously applied unconditionally to other flavors.

66effde97d Merge remote-tracking branch 'origin/topic/seth/624'
* origin/topic/seth/624:
  Support whitespace at end of line for config reader.

This merge fixes a failing test; it also sprinkles a few more spaces
into another test file.

The main change is that this now also works with configuration lines
that don't have a value.

289a1e2e8e Merge branch '555-smb3-negotiate-context-fix' of https://github.com/mad/zeek
- Fixed the context list padding to only be used for dialect 0x0311.
  The new test case includes an example where parsing the optional
  padding would fail for another dialect.

6bc947a48e GH-474: add MQTT::max_payload_size option
This caps size of payload strings within mqtt_publish events and
mqtt_publish.log files.  A new "payload_len" field in the log file
shows the real payload size in cases where it may have been truncated.

6f25125443 Update CA store to NSS 3.45

was removed from the Mozilla store - the test now directly includes that
specific root-cert.

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

07e0dba3c6 Add DPD::max_violations option
This allows one to tune the number of protocol violations to tolerate
from any given analyzer type before just disabling a given instance
of it.

Also removes the "disabled_aids" field from the DPD::Info record
since it serves no purpose: in this case, calling disable_analyzer
multiple times for the same analyzer is a no-op.
