+ nftables support implemented for ipset
  + Added table_v4, table_v6 and mode parameters
    for ipset. Mode parameter can be 0 for iptables
    or nonzero for nftables.
  * Some small refactoring of iptables code occured

  ! fixed ipset table name for ipv6
    was always same with set name
  * correct nl netflter header family constant
  * all used nft tables must be created
    in inet family now
  ! fixed processing not A or AAA records
