The loop over Reducers in SumStats::observe performs a key normalization
and inadvertently modifies the key used for subsequent iterations.
Reported by Jim Mellander.
Now defaults to a max of 4 threads typically indepedent of core
count (previously could go up to a hard cap of 8). Also now allow
controlling this setting via BRO_BROKER_MAX_THREADS environment
variable.
* origin/topic/vern/vec-append:
d'oh, still have a (deprecated) string_array rather than string_vector
forgot to update test suite results for v += e
reap the fruits of v += e
test case for v += e
documentation of v += e
v += e implemented
Fixed a mistake in find_ip_addresses()
* origin/topic/vern/perf-history:
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.
This updates the "lookup_location" and "lookup_asn" BIFs to use
libmaxminddb. The motivation for this is that MaxMind is discontinuing
GeoLite Legacy databases: no updates after April 1, 2018, no downloads
after January 2, 2019. It's also noted that all GeoIP Legacy databases
may be discontinued as they are superseded by GeoIP2.

* origin/topic/johanna/config-cluster:
Add vector to read_config_cluster test.
Fix special-case-bug for vectors in UnaryExpr.
Config: another cluster test-case, this time reading in a file.
Add sending of values to nodes that dropped out.
Continue work on config framework clusterization.
Teach Option::set to unwrap Broker::Data values
Start clusterizing configuration framework.
The former replaces the pcap vs. live versions of the same tuning
option. If a user does not change these, Bro makes some internal
decisions that may help avoid performance problems on systems with high
core counts: the number of CAF threads is capped at 8 and the maximum
sleep duration for under-utilized threads is increased to 64ms (CAF's
default is 10ms).
These may be used to change the number of scheduler threads that the
underlying CAF library creates. In pcap mode, it's currently hardcoded
to the minimal 4 threads due to potentially significant overhead in CAF.
This environment variable is now set to listen only on IPv4 loopback
when running unit tests (instead of using the default INADDR_ANY).
This also moves some of the @loads out from init-bare.bro into a new
init-frameworks-and-bifs.bro in order to better support calling BIFs
(like `getenv`) from variable initializations in those particular
frameworks.
