7e9f4eb260 Track client requests through location manager.
This fixes a problem where applications could ask the location
manager to do very heavy-weight things (like...  say... update
location every minute), which would get accounted against the
system instead of the application because ultimately it is the
system making the heavy calls (wake locks, etc).

To solve this, we introduce a new class WorkSource representing
the source of some work.  Wake locks and Wifi locks allow you
to set the source to use (but only if you are system code and thus
can get the permission to do so), which is what will be reported
to the battery stats until the actual caller.

For the initial implementation, the location manager keeps track
of all clients requesting periodic updates, and tells its providers
about them as a WorkSource param when setting their min update time.
The network location provider uses this to set the source on the
wake and wifi locks it acquires, when doing work because of the
update period.

This should also be used elsewhere, such as in the GPS provider,
but this is a good start.

03ca216ac1 New Location Manager APIs for Criteria based requests and single shot mode.
Use MS-Assisted mode for single shot GPS fixes if it is supported.

Add finer grained control over accuracy to the android.location.Criteria class
and location criteria logic from LocationManager to LocationManagerService

3c8fbdf5dd location: dump LocationProvider internal state
For each location provider, call getInternalState() to see if it has any
state information to include in a bugreport. If the returned string is not
null, then print a header with the provided name followed by the returned
string.

d03ff94fe5 Clean up interface between LocationManagerService and the location providers:
LocationManagerService now uses new Java interface LocationProviderInterface
rather than LocationProviderProxy to refer to location providers internally.

LocationProviderProxy and the ILocationProvider binder interface are only
used for location providers implemented as services (NetworkLocationProvider)

Built-in location providers (GpsLocationProvider and mock providers) now just
implement LocationProviderInterface rather than using a Binder interface and proxy object.

Delete obsolete and unused TestLocationProvider class.

03d246779e GPS: Fix problem with SUPL when SUPL APN is already active.
Use ConnectivityManager.CONNECTIVITY_ACTION broadcast in LocationManagerService
to notify GPS when SUPL connection is ready instead of TelephonyIntents.ACTION_ANY_DATA_CONNECTION_STATE_CHANGED,
which is not sent in all cases.
Expand LocationProvider.updateNetworkState() to include NetworkInfo object.

Fixes bug b/2155661

fd6e5f0dda location: Replace ILocationCollector interface with new ILocationProvider method
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.

0528b9b26a location: Location Manager wakelock cleanup
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.

15e3d0f082 location: Use ILocationProvider Binder interface for all location providers.
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.

2f82c4eb0b location: Generalize support for location provider usage tracking.
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.

e932f7f2a4 AI 144663: Use Binder interfaces between NetworkLocationManager and LocationManagerService.
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.
