The attribute WGALLOWEDIP_A_IPADDR can contain either an IPv4
or an IPv6 address depending on WGALLOWEDIP_A_FAMILY, however
in practice it is enough to look at the attribute length.

This patch implements an ipv4-or-v6 display hint, that can
deal with this kind of attribute.

It only implements this display hint for genetlink-legacy, it
can be added to other protocol variants if needed, but we don't
want to encourage it's use.

I suspect there are occurrences of ipv4 or ipv6 in the existing specs
that really should be ipv4-or-ipv6 but the python code doesn't care.

I haven't been able to find any, containing 'ip' or 'addr'.

Speaking of display hints, then WGPEER_A_ENDPOINT is another interesting
case, it is struct sockaddr_in or struct sockaddr_in6, I have left that
as a plain binary for now, but maybe that could be a struct map, based
on struct length.

attribute-sets:
   -
     name: wgpeer
     [..]
     attributes:
       [..]
       -
         name: endpoint
         type: binary
         struct-map:
           - sockaddr_in
           - sockaddr_in6

With the requirement being, that all structs must have a unique length.
