japan gave us a new state table logic


get rid of that annoying address triple thing!

a state key has two addresses, src and dst
since src and dst are swapped depending on direction, just address1 and address2
same for ports

a state has two state key pointers: wire side and stack side
wire as seen on the wire
stack after pf is done with it
the above of course is exactly swapped when pf is called outbound
