- nftables-common is removed
- nftables-allports is obsolete, replaced by nftables[type=allports]
- nftables-multiport is obsolete, replaced by nftables[type=multiport]
* add [Init?family=inet6] to nftables-common.conf and make nftable
expressions more modular
* change "ip protocol" to "meta l4proto" in nftables-allports.conf
since the former only works for IPv4
