This fixes a hack that was added when NetworkLocationManager was moved out of the framework.
This also lays the groundwork for supporting location providers outside of the system process.

Move PhoneStateListener for listening to cell location changes from LocationManagerService
to the NetworkLocationProvider.
Move CellState class out of the core framework to the NetworkLocationProvider service.
NetworkLocationManager now notifies the collector of its state, rather than LocationManagerService.

Remove 1 Hz "heartbeat" polling of location providers from LocationManagerService.
Now location providers report their location to LocationManagerService via
LocationManager.setLocation() rather than waiting to be polled.
This reduces GPS fix latency by up to one second.
Remove LocationProvderImpl.getLocation().
Since we are no longer polling, this method is no longer necessary.

LocationManagerService now listens for changes to settings,
making LocationManager.updateProviders() unnecessary.
Removed LocationManager.updateProviders()
Added Settings.Secure.setLocationProviderEnabled(), which is a thread-safe way
of enabling or disabling a single location provider.
This is safer than reading, modifying and writing the LOCATION_PROVIDERS_ALLOWED directly.
