Log message:
Add kernel code to keep track of tcp connections which have completed
the 3-way handshake. Allow limits on both total connections and connection
rate, put offenders in a table which can be used in the ruleset, and optionally
kill existing states. Rate tracking code from dhartmei_(_at_)__(_dot_)_

Adds a second pool for table entries using the default allocator, which
allows entries to be added at splsoftnet().
