Initial implementation, tracking use of the vibrator, GPS,
and location reports.
Also includes an update to battery stats to also keep track of
vibrator usage (since I had to be in the vibrator code anyway
to instrument it).
The service itself is only half-done. Currently no API to
retrieve the data (which once there will allow us to show you
which apps are currently causing the GPS to run and who has
recently accessed your location), it doesn't persist its data
like it should, and no way to tell it to reject app requests
for various operations.
But hey, it's a start!

1. ViewRootImpl was keeping reference to the old focused view so it can
call back the global on focus change listener when another view gets
focus. The stashed reference, however was not cleared which caused a
memory leak if the last focused view was removed from the view tree.
In general keeping additional state for the last focus in ViewRootImpl
is not a good idea since this add complexity due to additional book
keeping work that is required. The view tree already keeps track of
where the focus is and it should be the only place that holds this
data. Since focus does not change that frequently it is fine to look
up the focus since this operation is O(m) where m is the depth of the
view tree. This change removes the duplicate book keeping from
ViewRootImpl and the focus is looked up as needed.
2. ViewRootImpl was calling the global focus change callbacks when focus
is gained, lost, or transferred to another view. This was done in
*ChildFocus methods. In the case of a child losing focus, i.e. in
clearChildFocus, there was a check whether focus searh yields a view
to take focus and if so it did not call back the global focus listener
assuming the the found view will take focus (the view tree gives focus
to the first focusable when a view looses focus). This is not a correct
assumption since some views override methods called as a result of
View.requestFocus that determine what the next focused view should
be. For example, HorizontalScrollView overrides onRequestFocusInDescendants
and changes the direction of the search. In fact focus search does not
take into accound ViewGroup descendant focusability. Hence, the view found
by calling the focus search from the root is not necessarily the one
that will get focus after calling requestFocus. Actually, it is
possible that the focus search will find a view but no view will
take focus. Now the View class is responsible for calling the
global focus listeners which avoids the above problem. Also this
saves book keeping in ViewRootImpl.

TTS Voice-data related API was originally written with
one engine in mind (pico sVox TTS). It exposes some implementation
details that should be private to the engine implementation.
- Deprecating fields of ACTION_CHECK_TTS_DATA results that were
used by sVox language packs to find out location of voice data.
Those fields are TTS engine implementation details and should be
private:
EXTRA_VOICE_DATA_ROOT_DIRECTORY
EXTRA_VOICE_DATA_FILES
EXTRA_VOICE_DATA_FILES_INFO
- Deprecating fields of ACTION_CHECK_TTS_DATA request that are
providing unnescesary functionality (it can be easily done on client
side):
EXTRA_CHECK_VOICE_DATA_FOR
- Deprecating some of the return codes of ACTION_CHECK_TTS_DATA - they
are specific to sVox pico voice data and in all cases can be replaced
by CHECK_VOICE_DATA_FAIL result code.
CHECK_VOICE_DATA_BAD_DATA
CHECK_VOICE_DATA_MISSING_DATA
CHECK_VOICE_DATA_MISSING_VOLUME
- Changing semantics of ACTION_TTS_DATA_INSTALLED intent. It's now
more generic and covers any change of available voice data set (so, not only
adding languages, but also removing them should trigger broadcast. Adding and
removing features to existing locale (like embedded synthesis) should be marked
by broadcast as well).
- Deprecating its EXTRA_TTS_DATA_INSTALLED result field - client should discover
the change by running ACTION_CHECK_TTS_DATA intent.
- Making GetSampleText intent public again - it's used by most TTS engines to
provide unique demonstation data.
- Deprecating TextToSpeech.OnUtteranceCompletedListener - it was replaced
by UtteranceProgressListener in API level 15, but no one put deprecation tag
on it.
