Hide new location APIs and undeprecate old ones
Hide all new location APIs related to LocationRequest/Geofence and
undeprecate all deprecated APIs consequently to the LocationRequest and
Geofence introduction. Also introduce LocationRequestUnbundled for
LocationProviders to use.

fix NLP for COARSE applications, build FLP with SDK
In this commit, we provide a means for unbundled location providers
to attach an EXTRA_NO_GPS_LOCATION to the Locations that they report.
We also build FusedLocation against the SDK rather than the internal
tree.
Used in conjunction with I394ded497b8de40d1f85618bff282553cdf378cb
to fix NLP for applications with only ACCESS_COARSE_LOCATION
permission.

Simplify fused location provider.
The previous location fusion algorithm produced very poor results
outdoors, where stale-but-accurate network locations had too much
influence over the final fused location.
I swapped the previous fusion algorithm out with an algorithm
that has been well-tested elsewhere and should produce superior
results.

Changes to support updating location providers.
There is now only a single config value pointing
at a list of packages to get certs from. The old
system was a bit confusing.
The fused location provider also now builds
against SDK 17, and the meta data service version
tag was renamed from the overly generic "version"
to "serviceVersion".

Do not use passive GPS data for COARSE only apps.
FusionEngine now attaches a secondary location that has never seen
GPS data to its result. LocationFudger uses the GPS-less location so
that COARSE apps never see data from the GPS provider.
When the previous location is updated, the previous GPS-less location
is carried over if the location update was GPS-only.
Additionally, apps without FINE permission are not notified when GPS
location changes, and any attempt to use GPS_PROVIDER without FINE
permission is met by a stern SecurityException.

Fix a couple of bugs from the location overhaul.
Marshall LocationRequest array correctly.
Observe reportLocation from FusionEngine.
Actually deliver the setRequest message to fusion engine.

Location overhaul, major commit.
Themes: Fused Location, Geofencing, LocationRequest.
API changes
o Fused location is always returned when asking for location by Criteria.
o Fused location is never returned as a LocationProvider object, nor returned
as a provider String. This wouldn't make sense because the current API
design assumes that LocationProvider's have fixed properties (accuracy, power
etc).
o The fused location engine will tune itself based on the criteria passed
by applications.
o Deprecate LocationProvider. Apps should use fused location (via Criteria
class), instead of enumerating through LocationProvider objects. It is
also over-engineered: designed for a world with a plethora of location
providers that never materialized.
o The Criteria class is also over-engineered, with many methods that aren't
currently used, but for now we won't deprecate them since they may have
value in the future. It is now used to tune the fused location engine.
o Deprecate getBestProvider() and getProvider().
o Add getLastKnownLocation(Criteria), so we can return last known
fused locations.
o Apps with only ACCESS_COARSE_LOCATION _can_ now use the GPS, but the location
they receive will be fudged to a 1km radius. They can also use NETWORK
and fused locatoins, which are fudged in the same way if necessary.
o Totally deprecate Criteria, in favor of LocationRequest.
Criteria was designed to map QOS to a location provider. What we
really need is to map QOS to _locations_.
The death knell was the conflicting ACCURACY_ constants on
Criteria, with values 1, 2, 3, 1, 2. Yes not a typo.
o Totally deprecate LocationProvider.
o Deprecate test/mock provider support. They require a named provider,
which is a concept we are moving away from. We do not yet have a
replacement, but I think its ok to deprecate since you also
need to have 'allow mock locations' checked in developer settings.
They will continue to work.
o Deprecate event codes associated with provider status. The fused
provider is _always_ available.
o Introduce Geofence data object to provide an easier path fowards
for polygons etc.
Implementation changes
o Fused implementation: incoming (GPS and NLP) location fixes are given
a weight, that exponentially decays with respect to age and accuracy.
The half-life of age is ~60 seconds, and the half-life of accuracy is
~20 meters. The fixes are weighted and combined to output a fused
location.
o Move Fused Location impl into
frameworks/base/packages/FusedLocation
o Refactor Fused Location behind the IProvider AIDL interface. This allow us
to distribute newer versions of Fused Location in a new APK, at run-time.
o Introduce ServiceWatcher.java, to refactor code used for run-time upgrades of
Fused Location, and the NLP.
o Fused Location is by default run in the system server (but can be moved to
any process or pacakge, even at run-time).
o Plumb the Criteria requirements through to the Fused Location provider via
ILocation.sendExtraCommand(). I re-used this interface to avoid modifying the
ILocation interface, which would have broken run-time upgradability of the
NLP.
o Switch the geofence manager to using fused location.
o Clean up 'adb shell dumpsys location' output.
o Introduce config_locationProviderPackageNames and
config_overlay_locationProviderPackageNames to configure the default
and overlay package names for Geocoder, NLP and FLP.
o Lots of misc cleanup.
o Improve location fudging. Apply random vector then quantize.
o Hide internal POJO's from clients of com.android.location.provider.jar
(NLP and FLP). Introduce wrappers ProviderRequestUnbundled and
ProviderPropertiesUnbundled.
o Introduce ProviderProperties to collapse all the provider accuracy/
bearing/altitude/power plumbing (that is deprecated anyway).
o DELETE lots of code: DummyLocationProvider,
o Rename the (internal) LocationProvider to LocationProviderBase.
o Plumb pid, uid and packageName throughout
LocationManagerService#Receiver to support future features.
