IPv6 connectivity might start off (e.g. network not fully up when haproxy starts), so for features like resolvers, it would be nice to periodically recheck. With this change, instead of having the resolvers code rely on a variable indicating connectivity, it will now call a function that will check for how long a connectivity check hasn't been run, and will perform a new one if needed. The age was set to 30s which seems reasonable considering that the DNS will cache results anyway. There's no saving in spacing it more since the syscall is very check (just a connect() without any packet being emitted). The variables remain exported so that we could present them in show info or anywhere else. This way, "dns-accept-family auto" will now stay up to date. Warning though, it does perform some caching so even with a refreshed IPv6 connectivity, an older record may be returned anyway.
