39bdc397a0 DTLS: Fix interaction with STUN
Now the DTLS analyzer cleanly skips all STUN messages; no warnings
should be logged to dpd.log and parsing should work flawlessly with
intermixed STUN messages.

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.

function to "send_event" because Bro shows a syntax error when a
Bro script function is named "event" or "print".

e9a87566ef Fix parsing of x509 pre-y2k dates
There was a bug in the new parsing code, introduced in
708ede22c6 which parses validity times
incorrectly if they are before the year 2000. What happens in this case
is that the 2-digit year will be interpreted to be in the 21st century
(1999 will be parsed as 2099, e.g.).

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.

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.

subnet.

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.

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.

* 'patch-4' of https://github.com/aeppert/bro:
  (BIT-1545) Add "disable_analyzer_after_detection" en lieu of "skip_processing_after_detection"

I also removed the old disable_analyzer_after_detection option
completely - if someone wants that, they can just catch the event
themselves and call skip_further_processing.

I also adjusted the ssh test case to contain conn.log to prevent
re-addition of this problem in the future.

a38327bd08 Extend NetControl logging and fix bugs.
Netcontrol log now includes more information; before that, it had not
quite caught up to the new capabilities (like flow modifying and
redirection, as well as mac addresses).

Furthermore, this fixes a number of bugs with cluster mode (like
duplicate events), test failures due to updates in Bro, etc.

9f3c0c9bb4 Update OpenFlow API and events.
Events now generally carry the unique ID of the backend that is given
during initialization; there are a few more functions and other
bugfixes.

A few netcontrol tests are still broken (mostly due to a pcap update in
msater).

642ef5d3c1 Tweaking how HTTP requests without URIs are handled.
The change from #49 made it an error to not have a URI. That however
then led requests with an URI yet no version to abort as well.
Instead, we now check if the token following the method is an "HTTP/"
version identifier. If, so accept that the URI is empty (and trigger
a weird) but otherwise keep processing.

Adding test cases for both HTTP requests without URI and without
version.

401e6c9102 Extend ssl dpd signature to allow alert before server_hello.
The alert in this case is caused by the server name in the SNI not being
recognized by the server, which triggers an alert. Since the server is
an apache, and this might happen reasonably often, the new signature
allows one TLS alert before the server hello is expected.
