This patch reduces the size of 'struct ip_conntrack' on systems with NAT
by eight bytes. The sequence number delta values can be int16_t, since
we only support one sequence number modification per window anyway, and
one such modification is not going to exceed 32kB ;)

When 'rustynat' was merged in 2.6.12, the use of the "helper" pointer of
struct ipt_nat_info was obsoleted, but the pointer not removed from the
struct.
This patch removes the pointer, thereby yet again shrinking struct
ip_conntrack.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
