Improve IP address list representation in libxo output.

Extract decision-making about special-case printing of certain
jail parameters into a function.

Refactor emitting of IPv4 and IPv6 address lists into a function.

Resulting user-facing changes:

XO_VERSION is bumped to 2.

In verbose mode (-v), IPv4 and IPv6-Addresses are now properly emitted
as separate lists.
This only affects the output in encoding styles, i.e. xml and json.

}                                    }

In -n mode, ip4.addr and ip6.addr are formatted in the encoding styles'
native list types, e.g. instead of comma-separated lists, JSON arrays
are printed.

jls -n all --libxo json
 ...
 "ip4.addr": [
    "10.1.1.1",
    "10.1.1.2",
    "10.1.1.3"
  ],
  "ip4.saddrsel": true,
  "ip6.addr": [
    "fe80::1000:1",
    "fe80::1000:2"
  ],
  ...

jls -n all --libxo xml
  ...
  <ip4.addr>10.1.1.1</ip4.addr>
  <ip4.addr>10.1.1.2</ip4.addr>
  <ip4.addr>10.1.1.3</ip4.addr>
  <ip4.saddrsel>true</ip4.saddrsel>
  <ip6.addr>fe80::1000:1</ip6.addr>
