A race condition could cause unstable output: if the thread reading the
file is fast, often you see both "pred" functions execute and then both
"line" events execute with both entries already in the table, but if the
thread reading the file is slow, you see pred, event, pred, event, with
only one entry available in the first event.
The order in which &expire_func's get called isn't well-defined, so
separate the output from either to ensure diffs against the Baseline are
always consistent.
* Generally increase timeouts for tests that have recent transient
failures
* Change any test that relied on `btest-bg-wait -k` since that's never
going to play with with CI systems. Instead, we always need to have
a well-defined termination condition in the test itself (and most
already did, so didn't really need the `-k` flag anyway).

Logs that got sent sparsely or burstily would get buffered for long
periods of time since the logic to flush them only does so on the next
log write. In the worst case, a subsequent log write could never happen
and cause a log entry to be indefinitely buffered.
This fix introduces a recurring event/timer to simply flush all pending
logs at frequency of Broker::log_batch_interval.
This change standardizes threading formatter error handling and moves
the remaining error calls to be warnings instead.
This is in line with already existing code - in most cases warnings were
raised, only a few cases raised errors. These cases do not differ
significantly from other cases in which warnings are raised.
This also fixes GH-692, in which misformatted lines prevent future file
parsing.
This commit also moves the FailWarn method that is used by both the
config and the ascii reader up to the ReaderBackend. Furthermore it
makes the Warning method of ReaderBackend respect the warning
suppression that is introduced by the FailWarn method.
The Zeek code base has very inconsistent #includes. Many sources
included a few headers, and those headers included other headers, and
in the end, nearly everything is included everywhere, so missing
#includes were never noticed. Another side effect was a lot of header
bloat which slows down the build.
First step to fix it: in each source file, its own header should be
included first to verify that each header's includes are correct, and
none is missing.
After adding the missing #includes, I replaced lots of #includes
inside headers with class forward declarations. In most headers,
object pointers are never referenced, so declaring the function
prototypes with forward-declared classes is just fine.
This patch speeds up the build by 19%, because each compilation unit
gets smaller. Here are the "time" numbers for a fresh build (with a
warm page cache but without ccache):

During merge I split the test for bro_init/bro_done/bro_script_loaded
event errors into individual tests since the other testing of the zeek
versions of those events seemed fine to otherwise keep.

I'd expect the portnum component to remain uninitialized in case the
given URI specifies no port number -- however, decompose_uri() raises an
error instead. Will address this in a subsequent commit.
We now have an &broker_store attribute which automatically sends
inserts/deletes into a set/table to broker.
This might work - I actually did not test if the data ends up in the
broker store in the end. A limitation is that the table/set currently
only can have a one-element type since Broker doesn't support the list
type.
Tweaks:
- Small change to the logic for removing quotes around strings.
- Updated NEWS & COPYING.3rdparty
- Use of intrusive_ptr for stack-allocated StringVals
- Little bit of refactoring (I would love to merge the two BuildJSON() functions, too, but that's a larger task)
