Internal cleanup for Animator framework
This CL includes the following changes:
1) Remove redundant field mPlayingState in ValueAnimator.
2) Refactor AnimationHandler so that all of its interaction with Choreographer
is through an interface. A custom provider that implements this interface can
be plugged in and provide timing pulse that are independent of Choreographer.
3) Better encapsulate AnimationHandler and ValueAnimator. Interaction between
the two is done through register/unregister frame callbacks as well as
AnimationFrameCallback interface.
4) Change how animation delay is handled.

Fix animation start jank due to expensive layout operations.
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.

Fix seeking and scaled duration behavior
The animation scaled was not being factored in early enough in the
activity lifecycle. Also, setCurrentPlaytTime() was not accounting for
the scaled duration correctly. Finally, added setCurrentFraction() as
a more general-purpose seeking facility.
Issue #18222006 Animator duration scale ignored in some situations
Issue #17951668 add ability to seek fraction, not just time

New status bar capable of multiple sliding panels.
There are some visual glitches but almost everything should
be put back pretty much where it was.

Use choreographer frame time to schedule animations.
Instead of using the current uptime millis, which can exhibit
substantial jitter depending on when the code runs, use the
current frame's vsync time when performing animations. The frame
time provides a more consistent pulse.

Make the TimeAnimator class public.
This class has existed since ICS, but was hidden. This change
just makes it public API.
Also, cleaned up some internal javadocs.

Adding TimeAnimator capability (hidden for now)
This new class allows listeners to receive callbacks with elapsed time
that are sent on the same animation updates as other animators in the system.
It will allow simulations that go beyond the current animation system while
handling the actual animation timing system and ensuring that those
simulations sync up with other typical animations.
