Commandline parsing was widely identical with iptables and ip6tables. This series adds the necessary code-changes to unify the parsers into a common one. Changes since v2: - Drop quirks for ignoring bogus table names and '-m' options, they likely just hide bugs. - Rewrite empty interface name quirk patch, make arptables-nft print iptables' error message as warning to notify users. - Integrate intrapositioned negation support into the final merge patch and revive iptables' old warning to notify users. Changes since v1: - Fix patch 12, the parser has to check existence of proto_parse callback before dereferencing it. Otherwise arptables-nft segfaults if '-p' option is given. - Patches 13-17 add all the arptables quirks to restore compatibility with arptables-legacy. I didn't consider them important enough to push them unless someone complains. Yet breaking existing scripts is bad indeed. Please consider them RFC: If you consider (one of) them not important, please NACk and I will drop them before pushing.
