This introduces a new phase of device idle mode, immediately before going idle (once we are sure the device is not moving), try to collect a location for the device so that any later requests for it will have a good chance of having an accurate value. We do this with two location requests: one a single-shot as accurate as possible location, and a second longer-running attempt to get an accurate location from the GPS. There is a limit on how long we will try to collect the location (default is 30 seconds), and we stop collection once we reach a desired accuracy (default is 20 meters). Also cleanup various transition paths out of the normal state flow to clean up any active state we may have running. Change-Id: Ibd3d2e9a720fbfd9640755baf5547180dd409f6a
