This change replaces ILocationCollector with a more general mechanism that
passes locations received from a provider to all other providers.
The network location provider now uses this to implement the location collector.
In the future, this could be used to inject network locations to the GPS
as aiding data.
This change also removes the now obsolete permission INSTALL_LOCATION_COLLECTOR.

Location Providers are now responsible for their own wakelocks and scheduling.
Also fixed a deadlock in LocationManagerService in the code for releasing
wakelocks after client notifications have been received.
The fix is to use the Receiver object and mWakeLock for synchronization
instead of the global mLock lock.

Also added new permissions android.permission.INSTALL_LOCATION_PROVIDER
and android.permission.INSTALL_LOCATION_COLLECTOR to the public API.

This change eliminates the LocationProviderImpl class which had been used
for location providers running in the system process.
Now the LocationProvider base class is only used to implement the
LocationManager.createProvider() method for retrieving provider information.
Added a new IGpsStatusProvider interface for providers that serve GPS status.

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.
