		- (nm_get_hal_ctx): new function, move Hal initialization code here
		- (nm_hal_init): new function, init libhal context then add devices
		- (nm_hal_deinit): new function, clean up libhal context
		- (nm_data_free): Move Hal cleanup here
		- (main): check whether Hal is running, and if so, get a list of
			network devices from it

	* src/NetworkManagerDbus.c
		- (nm_dbus_signal_filter): trap NameOwnerChanged signals for Hal,
			and when it appears, get a list of network devices from it.  If
			Hal goes away, clean up the libhal context
