Handle IP over IP (IPPROTO_IPV4) properly.
We now unwrap IP/IP and apply filter rules to both the outer
layer (with ``set filter blah x.x.x.x y.y.y.y ipip'') and to
the payload (reinterpreted by the filter rules).
``set log tcp/ip'' will now show both the outer wrapper and
the (reinterpreted) payload contents.
