d91dd8d9a8 Fix Bro and unit tests when broker is not enabled
When Bro was compiled with broker disabled, then some Bro scripts
were referencing functions and types that were not defined.  Fixed
by adding @ifdefs to several scripts.  Removed one @ifdef because
it was causing several unit tests to fail.

Also fixed the @TEST-REQUIRES check in tests that rely on broker so
that such tests are skipped when broker is disabled.

f44bb4d9b8 Add script wrapper functions for broker BIFs
Also renamed the "print" function to "send_print" and the "event"
function to "send_event" because Bro shows a syntax error when a
Bro script function is named "event" or "print".

41606e18fb Intel: Allow to provide uid/fuid instead of conn/f.
This patch allows users to provide the fuid or the connection id
directly, in case they do not have access to either in the event that
they handle.

An example for this is the handling of certificates in SSL, where the
fa_file record cannot be retained because this would create a cyclic
data structure.

This patch also provides file IDs for hostname matches in certificates,
which was not possible with the previous API.

04dd65cbaf Implement protocol confirmation
Do not set the service field in the bro script but
use the protocol confirmation paradigm.

Protocol is considered confirmed if both a
succesful client and server banner have been
parsed.

849875e8be Analyzer and bro script for RFB protocol (VNC)
This analyzer parses the Remote Frame Buffer
protocol, usually referred to as the 'VNC protocol'.

It supports several dialects (3.3, 3.7, 3.8) and
also handles the Apple Remote Desktop variant.

It will log such facts as client/server versions,
authentication method used, authentication result,
height, width and name of the shared screen.

It also includes two testcases.

Todo: Apple Remote Desktop seems to have some
bytes prepended to the screen name. This is
not interepreted correctly.

cafae5351b Added support for subnets to intel-framework.
The intel-framework now supports the new indicator type Intel::SUBNET.
As subnets are matched against seen addresses, the field matched was
introduced to indicate which indicator types caused the hit. A testcase
for subents was added and the old ones have been updated accordingly.

08399da6cb Files transferred over FTP were showing incorrect sizes.
The server-reported file size was being collected poorly and if
a file name had a number in it, that was reported as the file
size instead of the actual size.

A new test is included to avoid reintroducing the problem.

7ef431808d Rewrite internal handling of rules.
This has no user-facing changes. It makes the internal handling of rules
much easier (no crazy duplicate rules in case our rules are added to
several backends).

It also fixes several open ends and small bugs in the process.

562e5a9f63 Add bif that allows searching for all matching subnets in table.
Example:

global test: set[subnet] = {
	10.0.0.0/8,
	10.1.0.0/16,
	10.2.0.0/16,
	10.2.0.2/31
}

print matching_subnets(10.2.0.2/32, test);
->
[10.2.0.2/31, 10.2.0.0/16, 10.0.0.0/8]

42e4072673 Add signaling of succesful initialization of plugins to NetControl.
This does not really have many user-facing changes. The one big change
is that users now should initialize plugins in the

NetControl::init()

event instead of bro_init.

Once all plugins finished initializing and the NetControl framework
starts operations, the NetControl::init_done() event is raised.

Rules that are sent to NetControl before the plugins have finished
initializing are ignored - this is important when several plugins that
require external connections have to be initialized at the beginning.
Without this delay, rules could end up at the wrong plugin.

d9459fc59a Add rule hooks to the acld plugin.
The hook name is NetControl::acld_rule_policy and allows the
modification of acld rules before they are sent out to the network.

This allows, e.g. network policies to use nullzero instead of drop in
certain circumstances.
