Add two features:

    log_in_vain:
	log_in_vain turns on logging for packets to ports for which
	there is no listener.
    rc.sysctl:
	A generic way to set sysctl values.  It reads /etc/syslog.conf
	and sets values based on that.  No /etc/syslog.conf has been
	checked in yet, and I've not added this to the makefile yet
	until I get more feedback.
