Move the 'carrier' property from NMDevice to NMDevice8023Ethernet;
	convert the libnm-glib NMDevice8023Ethernet to cached properties

	* introspection/nm-device-802-3-ethernet.xml
		- New 'Carrier' property
		- New 'PropertiesChanged' signal

	* introspection/nm-device.xml
		- Remove 'Carrier' property
		- Remove 'CarrierChanged' signal

	* src/nm-device-interface.c
	  src/nm-device-interface.h
		- (nm_device_interface_init): remove 'carrier' property and
			'carrier-changed' signal

	* src/nm-device.c
	  src/nm-device.h
		- (nm_device_get_carrier, nm_device_set_carrier): remove
		- (nm_device_activate_stage5_ip_config_commit): don't bother updating
			the link here; wired device will handle that
		- (handle_dhcp_lease_change): don't bother updating link here
		- (get_property, nm_device_class_init): remove carrier property

	* src/nm-device-802-11-wireless.c
		- (real_update_link, nm_device_802_11_wireless_class_init): remove
			real_update_link(); wireless devices don't use carrier at all
		- (link_timeout_cb, supplicant_iface_state_cb_handler,
		   supplicant_iface_connection_state_cb_handler,
		   supplicant_mgr_state_cb_handler): remove anything to do with carrier

	* src/nm-device-802-3-ethernet.c
	  src/nm-device-802-3-ethernet.h
		- (nm_device_802_3_ethernet_carrier_on,
		   nm_device_802_3_ethernet_carrier_off, constructor): use set_carrier()
			instead of nm_device_set_carrier()
		- (device_state_changed): update link from sysfs on activation;
			replaces real_update_link()
		- (real_update_link): remove, replaced by device_state_changed()
		- (nm_device_802_3_ethernet_get_carrier, set_carrier): new functions
		- (nm_device_802_3_ethernet_get_speed): move up with other getters/setters
		- (real_get_generic_capabilities, real_can_interrupt_activation): use
			new get_carrier function
		- (get_property): add 'carrier' property
		- (nm_device_802_3_ethernet_class_init): add 'carrier' property and
			hook into property-changed signal helper

	* src/NetworkManagerPolicy.c
		- (device_carrier_changed): will only ever be called with a wired device
		- (device_added): only hook up to carrier-changed for wired devices

	* libnm-glib/nm-device.c
	  libnm-glib/nm-device.h
		- (constructor, nm_device_class_init): remove carrier-changed signal
		- (device_carrier_changed_proxy): remove; unused
		- (nm_device_get_carrier): remove; carrier a property of wired devices

	* libnm-glib/nm-device-802-3-ethernet.c
	  libnm-glib/nm-device-802-3-ethernet.h
		- Convert to cached properties like AP and Wireless objects
		- (nm_device_802_3_ethernet_get_hw_address): now returns a 'const char *'
			instead of a 'char *', return value should not be freed
		- (nm_device_802_3_ethernet_get_carrier): return current carrier status
		- (constructor): hook into properties-changed helper
		- (set_property, get_property): new functions
		- (nm_device_802_3_ethernet_class_init): export GObject properties

	* test/nm-tool.c
		- (detail_device): strdup the wired hardware address too since it's
			cached now

	* libnm-glib/libnm-glib-test.c
		- (dump_wired): strdup the wired hardware address too since it's
			cached now
