The prototype of ip_route_me_harder changed in 2.6.18.5, so I think
Xtables-addons should account for it. This renders compilation on
anything below it impossible. (2.6.17 is not supported in general.)
The Xtables-addons compat layer does not support pskb relocation
(result of possible memory allocation in kernels before 2.6.24) and
we just assume it does not happen. Add a check to warn if relocation
did happen and packet loss is to be expected.
Some code already uses ip_hdr() functions which did not exist in
2.6.21 and I do not feel like adding more compat code.

The extension modules use the API of a fairly recent kernel, if not
even the networking git tree. To make it work with older Linux
kernels, an API wrapper is added. Should compile against
running-kernels Linux 2.6.19..current (tested: 2.6.22..current).
