This is a convenience method for creating a GNetworkAddress which is guaranteed to return IPv4 and IPv6 loopback addresses. The program cannot guarantee that 'localhost' will resolve to both types of address, so programs which wish to connect to a local service over either IPv4 or IPv6 must currently manually create an IPv4 and another IPv6 socket, and detect which of the two are working. This new API allows the existing GSocketConnectable machinery to be used to automate that. Based on a patch from Philip Withnall. https://bugzilla.gnome.org/show_bug.cgi?id=732317
