iptables: Split the iptables modules into separate packages
PATCH 1/1 iptables: Split the iptables modules into separate packages
By splitting the iptables modules into separate packages it is possible to pick and choose the modules to install and thereby reduce the total size of the installed modules.
Backwards compatibility is maintained by adding a recommendation of iptables-modules, which is a meta package that depends on all the generated packages.

In our case we could save more than 1 MB by removing modules we do not use.
