NFLOG and NFQUEUE targets' full support for iptables.
Includes all needed kernel modules (Xtables's and Netlink's)
and userspace libraries.
All added kernel modules can be individually disabled,
all other new libraries get their own individual packages.

This patch merges the work from:
- ddx0n which got initially submitted in 2011 as patch in ticket #9969
and completed with the kmod-ipt-nfqueue module by me
- Fabian Hugelshofer he initially submitted in 2008 as patch on openwrt-devel which...
- ...Rainer Poisel reworked and resend there in 2010 which...
- ...Derek LaHousse reworked and resend there in 2013 (!).
I hope all this work can be finally submitted.
Please be kind as this is my first OpenWrt patch!
