Do not use passive GPS data for COARSE only apps.

FusionEngine now attaches a secondary location that has never seen
GPS data to its result. LocationFudger uses the GPS-less location so
that COARSE apps never see data from the GPS provider.

When the previous location is updated, the previous GPS-less location
is carried over if the location update was GPS-only.

Additionally, apps without FINE permission are not notified when GPS
location changes, and any attempt to use GPS_PROVIDER without FINE
permission is met by a stern SecurityException.
