Location overhaul, major commit.

Browse Source 
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.

TODO: The FLP and Geofencer have a lot of room to be more intelligent

(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:

wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.
