The Choreographer carefully schedules animation updates to occur
after input but before traversals occur. This ensures that the
effects of animations are perceived immediately in the next frame.
The start time of animation is usually set the moment the animator
first runs. The start time serves as a reference for timing the
remainder of the animation.
Setting the start time during the animation callback works well except
when traversals take a long time to complete. In that case, we may
end up drawing the initial frame of the animation then skipping several
following frames (because a lot of time has already passed since the
animation start time was set), effectively shortening the duration
of the animation.
To resolve this issue, we introduce a new COMMIT phase within the
Choreographer. The COMMIT callback runs after traversals complete
and may provide an updated frame time that more accurately reflects
the time when the frame finished drawing.
In the case where an animation is just starting, we note the fact
that its initial start time has not yet been committed (the user
hasn't actually seen anything on screen yet). Then, during the
COMMIT phase, we adjust the animation start time to better reflect
the time when the animation's first frame was drawn, effectively
causing the animation actually start after the expensive traversal
operations occurred such that no frames will be skipped.

Also adds a test app for testing this intent. In addition, the secure
camera gets launched in the background to fix jank while sending the
intent.

If SpanSet.init() is called several times in a row with different
values, it is possible to change "numberOfSpans" in a way that
will prevent SpanSet.recycle() from nulling out all the spans.
This can lead to memory leaks of large objects through spans
references. User @piwai reported this leak:
com.squareup.marketfont.MarketSpan
`-[1] of array android.text.style.CharacterStyle[]
`-spans of object android.text.SpanSet
`-mCharacterStyleSpanSet of object android.text.TextLine
`-[1] of array android.text.TextLine[]
`-sCached of class android.text.TextLine
The MarketSpan instance is kept alive through a recycled TextLine
which itself contains a SpanSet.

Currently worker threads in computeBestConfiguration may NOT completely
finish before timeout. But the code will start using the result while
the worker threads are still working on the same object. This may
cause exceptions.

Introduced new 'extractNativeLibs' attribute to manifest/application.
Setting it to false prevents installer from extracting library from apk.
The default value for extractNativeLibs is true.
