This commit rewrites catch and release, fixing issues with it and making
it fully cluster capable. A dedicated netcontrol_catch_release.log is
also added.
This is not quite done yet; a few more log messages are missing. There
should hopefully not be many big issues left.
This introduces two new events, NetControl::rule_new and
NetControl::rule_destroyed, which are raised when rules are first added
and then deleted from the internal state tracking.

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.
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.
