There may be some race conditions in the gps provider where it can cause a uid
to be double booked for gps usage and never released. Address this by tweaking
some locking (so mLocation and the uid array are protected by a lock both when
reading and writing). Also add some code to log a warning if someone tries to
note a particular uid multiple times, since the code will break in that case.
Finally, fix a problem in the battery stats where we weren't allowing a new Uid
structure to be created in many cases for calls coming in.
The GPS engine needs the hostname for the secure SUPL case
and deferring the DNS lookup to the HAL might be helpful in the future
if the SUPL server is on a carrier's private network.

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.

This will prevent us from keeping the processor awake indefinitely if a
background service is requesting periodic updates and we are unable to get a fix.

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.

64 satellties are required for NavStar, WAAS, EGNOS, and GLONASS satellites.
Increasing to 255 allows for future compatibility with Galileo.

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.

Now that we have GPS support in the emulator and public APIs for mock providers,
the fake provider support is no longer needed.

Remove two second timeout for wakelock when broadcasting events to
location listeners. Instead, hold wakelock until receipt of the event
is acknowledged, either via a Binder call or the
PendingIntent.OnFinished interface.

This replaces two different mechanisms that were used for GPS and Netork
location provider tracking.
Move BatteryStats logging of GPS usage from LocationManagerService to
GpsLocationProvider.
Clean up tracking of location listeners in LocationManagerService and remove
some HashMaps that are no longer needed.

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 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)

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.
