Kevin Easton 9427b3db84 Try all addresses returned by getaddrinfo() until we find one that socket() is happy with ...

Someone reported being unable to connect with the error "Address family not
supported", which is probably being returned by socket().  It is likely a
system where getaddrinfo() is returning AF_INET6 addresses, but socket()
won't create AF_INET6 sockets.

To handle this case, we loop over all the addresses returned by getaddrinfo()
until we find one that socket() will accept.
