Summary:
the reason for this is two-fold:
- getaddrinfo without the extra arguments will return the same
(network-level) address multiple times, once for each supported
transport protocol, which is not what is usually intended (it certainly
wasn't in D31823)
- it enables us to rewrite the getaddrinfo member function in terms of
the static GetAddressInfo function.
