- make each element of a variable hold a type - change get_type to take an index, so we can get the individual types of each element (since primitive elements can be in lists) - make port_range primitive - add a routine to convert a variable of primitives to a variable containing - only port ranges.

/* $NetBSD: npf_var.h,v 1.2 2012/02/26 21:50:05 christos Exp $ */
Full rewrite of npfctl(8) parser and rework of n-code generation part. Fixes most of the known bugs and issues with the utility. Note: rule procedures are not yet (as we want to make them fully modular). Huge thanks to Martin Husemann who wrote the parser and Christos Zoulas who wrote intermediate structures and helped to complete the work.
