This adds an event that is raised once Catch & Release ceases the
block management for an IP address because the IP has not been seen in
traffic during the watch interval.
This allows users who use their own logic on the top of catch and
release know when they will have to start re-blocking the IP if it
occurs in traffic again.
forgotten messages are only logged on the manager (or standalone host)
now. Logs are not written by default anymore when Bro encounters traffic
that should have been blocked.
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.
