Move broadcast receivers for wifi scan results and battery status
from LocationManagerService to NetworkLocationProvider
Add a Service for the NetworkLocationProvider, so we can install it from its
own thread rather than from BOOT_COMPLETED or callback from LocationManagerService.
(this Service was also required for receiving Intents in NetworkLocationProvider)

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.
