This is fixed now, but I have to see another testrun to confirm all
regression is addressed now.

For now, if the left= or right= is either an IPv6 address or contains
%defaultroute6 or %any6, it will set the hostaddrfamily to ipv6.
Otherwise it will set it to ipv4. Perhaps in the future we can use
something like gai.conf, but remember that currently a connection's
"this" end can only be ipv4 or ipv6 and not either.
