A long time ago I suggested splitting the one list we have today into several
lists, specifically:

	* per interface input list
	* per interface output list
	* packet forwarding list 
	* ip_input() list
	* ip_output() list

Doing it would be simple, but people complained that configuring it would
be too complex.

This would save a lot of time in complex filters.
