luigi 688d739fd8 preparation work to replace the monster switch in ipfw_chk() with
table of functions.

This commit (which is heavily based on work done by Marta Carbone
in this year's GSOC project), removes the goto's and explicit
return from the inner switch(), so we will have a easier time when
putting the blocks into individual functions.
