* libnm-glib/nm-device-802-11-wireless.c: Cache networks (bssids) list.
	We get signalled when it changes.

	* libnm-glib/nm-client.c: Cache NMState and device list, we get signalled
	when it changes.

	* libnm-glib/nm-device.c: Cache the device state property.

	* libnm-glib/nm-access-point.c: Cache the strength property.

	* src/nm-device-802-11-wireless.c: Fix wireless device scanning scheduler.
	The new algorithm is to start from SCAN_INTERVAL_MIN (currently defined as 0)
	and add a SCAN_INTERVAL_STEP (currently 20 seconds) with each successful scan
	until SCAN_INTERVAL_MAX (currently 120 seconds) is reached. Do not scan while
	the device is down, activating, or activated (in case of A/B/G cards).
	Remove some old dead ifdef'ed out code that used to configure wireless devices,
	it's all done through supplicant now.

	* src/supplicant-manager/nm-supplicant-interface.c: Fix the reference
	counting issues with pending calls which caused leaks and crashes when
	interface was removed (now that the interface actually gets removed).

	* src/nm-call-store.c: Make a copy of data before running a foreach
	with user callback on it - The most common usage pattern is to cancel
	(and thus remove) all pending calls with foreach which would modify
	the hash table we're iterating over.

	* src/nm-manager.c: When a device is added, make sure it is "up". When
	it's removed or disabled due to disabling wireless or networking, bring
	it down.

	* include/NetworkManager.h: Add new device state NM_DEVICE_STATE_DOWN.

	* src/nm-device-802-11-wireless.c: 
	* src/nm-device-802-3-ethernet.c: 
	* src/nm-device.c:
		- Remove "init" virtual function, all gobjects have a place for that
		  already (constructor).
		- Replace "start" virtual function with "bring_up", devices can be
		  brought up and down more than just on startup now.
		- Add "is_up" virtual function.
		- Implement one way to bring a device down instead of previous 4 different
		  ways, each of witch did something different.

	* src/NetworkManagerUtils.c (nm_dev_sock_open): This doesn't need an NMDevice,
	all it needs is the device interface.

	Get rid of NMData.dev_list (3 members to go).
	Get rif of NMData in a lot of places.

	* gnome/libnm_glib/libnm_glib.c: Make it compile again.
