Keeping AI_ADDRCONFIG is mandatory as this is required for correctly
operating IPv4/IPv6 dual stack support.
In tests/socket-helpers.h I have a couple of APIs designed to help
in this case.
int socket_can_bind_connect(const char *hostname);
int socket_check_protocol_support(bool *has_ipv4, bool *has_ipv6);
The latter function just calls the former with "127.0.0.1" and
"::1" and reports results =.
The intention is that any test which relies on using getaddrinfo()
should call one of these functions, and then skip any tests which
have a dependancy on this working.
We certainly don't do these checks it all our tests right now
though, so it is not surprising if some fail.
