Implements read/write of network stats using AtomicFile, along with
magic number and versioning. Stores in "/data/system/netstats.bin"
for now. Tests to verify that stats are persisted across a simulated
reboot, and to verify that TEMPLATE_WIFI is working.
Fixed bug where kernel counters rolling backwards would cause negative
stats to be recorded; now we clamp deltas at 0.

Note that this change is slightly more flexible, it defines
a priority for each playback request. We needn't really throw
away synthesis requests from other apps. We could just play
them after higher priority ones (for e.g from talkback).

Also updates the documentation to make clear how the encoding parameter should be used.

The usage feedback will be used for achieving per-method
(email address, phone number) ranking improvement.

This change adds a generic Property facility to the SDK, which allows an
easy way to reference fields (private or otherwise) in a general way.
For example, animations can use this facility to animate 'properties'
on target objects in a way that is more code- and compiler-friendly than
the existing String-based approach (for objects which have implemented
Properties, of course). The animator classes have been updated to use
this new approach (in addition to Strings, which are still more generally
useful for objects which have get/set functions but not Property objects).
The change also includes new Property objects on View (which can now be
used in creating animations on Views).
There is an unrelated change on GLES20RecordingCanvas to change the way we
cache bitmaps, which avoids spurious garbage by using an ArrayList instead of
a HashSet.

This ended up making the implementation a lot cleaner
as well. See the bug listed below for some background.

Will be launched by Settings when presenting detailed network data
usage for a specific application. Offers easy access into application
settings to change behavior.

When given a start/end range, interpolate between buckets to return
the total network usage. Used to summarize detailed UID stats. Method
to combine NetworkStatsHistory regardless of bucket size. Used to
combine all histories matching a template.
Added tests for both methods.

Collect UID-granularity network stats during regular poll event. Add
dumpsys argument to generate fake historical data for debugging, and
move stats parameters to Settings.Secure.
