device: Add temporary Start / StopAccessPoint Dbus methods
As a temporary DBus API to switch between Station and Access Point
modes, add two methods on the Device interface. Add a new state
DEVICE_STATE_ACCESS_POINT which is in effect from the moment
StartAccessPoint is received (even before it returns) until
StopAccessPoint returns, there are no intermediate states when the
methods run for simplicity. Add checks across device.c to make sure
Station related functionality is disabled when in Access Point mode.
