Please pull or apply from
	git://dev.medozas.de/iptables master

to receive:

[PATCH 1/5] libip6t_policy: remove redundant functions
[PATCH 2/5] policy: use direct xt_policy_info instead of ipt/ip6t
[PATCH 3/5] policy: merge ipv6 and ipv4 variant
[PATCH 4/5] build: fix manpage collection
[PATCH 5/5] extensions: use NFPROTO_UNSPEC for .family field

The xt_policy file layout kinda stood in the way a bit, so I felt
inclined to fix that. The manpage fix from Florian is ok, but can
be done a little simpler (see 4/5); the .c files receive updates
they should have gotten with v1.4.3-rc1-2-g03d9948 (5/5) to complete
the manpage collection group fix.

  To: pablo; +Cc: netfilter-devel

Florian Westphal points out that v1.4.3.2-9-gc304d77 greps for the
keyword in the wrong file, and that files with NFPROTO_UNSPEC are
skipped.

This patch corrects that part, and makes `make` now output the
manpages it collected.

This constant would be the designated one for the .family field; it
also, given recent changes, makes grep for NFPROTO_UNSPEC work to
finally recollect all manpages.
