* Changed ETHER_GET_LINK_STATE ethernet driver interface, added ETHER_SET_LINK_STATE_SEM.

* The device interface list now uses class DoublyLinkedList instead of struct list.
* Implemented SIOC[SG]IFMEDIA for setting (not supported by any device yet), and
  retrieving the device media information.
* Fixed a locking bug in list_domain_interfaces().
* Added new stack function device_link_changed() that should be called in case the
  link state (media) changed.
* The ethernet device module now spawns a thread and will periodically check the media
  state of all ethernet devices that support this (if any).
* Minor cleanup.
