- Alwasy explicitly bring the interface up before configuring it.

- If an interface's ifconfig_<ifn> is set, but empty, don't set it to
   ifconfig_DEFAULT.  This way interfaces can be disabled even in the
   presence of ifconfig_DEFAULT.
 - When listing interfaces and network_interfaces=auto, place lo0 first
   if it's around.
