Creates a new GSocketConnectable for connecting to the given
hostname and port.
Note that depending on the configuration of the machine, a
hostname of localhost may refer to the IPv4 loopback address
only, or to both IPv4 and IPv6; use
NetworkAddress.newLoopback to create a gio.NetworkAddress that
is guaranteed to resolve to both addresses.
