Fixing a make/compile issue with iptables, release candidate 1.4.0rc1,
which has existed since SVN changeset 6920. This patch adds ip_tables.h
and ip6_tables.h, and updates x_tables.h, taken from Linus'es git tree.
Changeset 6920 added the include file x_tables.h from kernel source, but
didn't add ip_tables.h and ip6_tables.h.
At some point (Tue Nov 14 19:48:48 2006, by Yasuyuki Kozakai) these
kernel headers where changed, which actually removes certain
depencencies from ip_tables.h and ip6_tables.h to x_tables.h.
If compiling will fail, with old kernel headers (ip_tables.h and
ip6_tables.h) available in systems include path, because they depend on
certaine defines in x_tables.h with is missing in the version in SVN.
