	dbus 0.30 api and new hal.

	* info-daemon/NetworkManagerInfoDbus.c:
		don't free null arrays.

	* panel-applet/NMWirelessAppletDbus.c:
	* src/nm-dbus-device.c:
	* src/nm-dbus-net.c:
	* src/NetworkManagerDbus.c: more
 	STRING -> OBJECT_PATH fun
	* src/NetworkManagerDevice.c:
	* src/NetworkManagerDevice.h:
	(rename nm_device_get_link_active): rename to
	nm_device_has_active_link
	(nm_device_wireless_link_active): rename to
	nm_device_probe_wireless_link_state
	(nm_device_wired_link_active): rename to
	nm_device_probe_wired_link_state.  Rewrite to
	use carrier file since hal doesn't maintain
	link state anymore.
	(nm_device_update_link_active): rename to
	nm_device_update_link_state
	* src/NetworkManagerPolicy.c
	  (nm_policy_activation_finish): check for NULL
	  MAC address.

	* src/NetworkManager.c:
	* src/nm-netlink-monitor.c:
	* src/nm-netlink-monitor.h: New class to support
	monitoring wired ethernet link status, since HAL
	doesn't export that information anymore.
