Adds the functions
NetControl::find_rules_addr and NetControl::fund_rules_subnet
which return a vector containing all rules affecting a certain IP or
subnet.
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.
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.
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.

* 'master' of https://github.com/marktayl/bro:
Better multi-space separator handling.
Also tweak multi-space separator handline some more and add test-case
triggering the new behavior.
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.
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).
* 'master' of https://github.com/marktayl/bro:
Removed duplicate parameter for IRC "QUIT" event handler.
Also add a test-case that checks the output of the quit
event handler.
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.
Cleaned up the surrounding code a bit and also added '[' as another
case (not sure that can happen, but doesn't hurt eihter).

Fix for JSON formatter
A fatal error, especially in DEBUG, should result in a core.
Seems to fix a case where an entry in the table may be null on insert.
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.
This is a very simple XMPP analyzer that basically only can parse the
protocol until the client and server start negotiating a TLS session. At
that point, the TLS analyzer is attached.
While the basic case seems to be working, I fully expect that I missed
something and that this might break in a lot of cases.
I've changed the dynamic allocation of the unzipbuf back to stack
allocation, hope I'm not not missing the reason for doing that ...
* origin/topic/seth/deflate-missing-headers-fix:
Fixes an issue with missing zlib headers on deflated HTTP content.
