* Function: copy_interface
* Purpose:
* Get a reference to an SCNetworkInterfaceRef for the specified
* interface name. First try to get an interface configured in the
* current set. If that fails, copy a service configured over the
* specified interface, and add it to the current set.
*
* Return the interface, service, and set for the caller to release.
