The current firstStrong value of textDirection is locale-dependent,
and can create problems when consistent display of text across
locales of potentially different direction is desired.
This adds two new values for textDirection, firstStrongLtr and
firstStrongRtl, which don't use the locale or the view's direction as
fallback, but explicit values of LTR or RTL.
Using firstStrongLtr also guarantees the exact algorithm defined in
the Unicode Bidirectional Algorithm to be used for determining
direction.

In order to preserve the same look and feel of an animation across different
devices, we need to maintain the same angular velocity for the animation in
users' field of view. Since the animation path may span different angles on
different devices, we need to therefore adjust the duration accordingly.

This CL adds the Activities that support Intent.ACTION_PROCESS_TEXT
to the Text Selection Action Mode in Editor, and triggers an intent
with the currently selected text when they are selected.
It also adds the required mechanism to allow a View to request an
intent to be started, and return the activity result back to it.

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.

Cleans up verbose R package in GridView, accessibility action docs,
and some lint warnings in AccessibilityNodeInfo. Makes the action IDs
for SHOW_ON_SCREEN and SCROLL_TO_POSITION public so that we can
guarantee they won't change (and thus reference them in support lib).

* changes:
Add test assist to implement motion study
Implement new assist gesture and motion
Add flag to voice interactor for supporting assist gesture
Add more internal API's for assist
Add ability to start voice interaction session directly
- When starting a voice interaction session from SysUI, a callback
can be passed to know when voice interaction has successfully started
- Add a new window type for the voice interaction starting window,
which resides behind the voice interaction layer.
- SystemUI now also inspects the voice interaction service to get the
logo asset for the starting window.
- Make VoiceInteractionSession window fullscreen, to accomodate for
the visuals.

New APIs on ViewAssistStructure all the app to request to
build a sub-tree asynchronously and indicate when it is done
with that. The overall AssistStructure is now only flattened
and transfered on-demand, when the app receiving it requests
its data -- and at that point we can wait for any asynchronous
building to complete.
New AsyncStructure view is a very simple example of using this
to asynchronously build a child view.

Instead of collecting all of the data directly in AssistStructure,
we now have a dispatch mechanism down the hierarchy to do so.
While doing this, also added the ability to automatically collect
assist data from AccessibilityNodeProviders attached to views
(so now we see all of the data in for example Calendar).
This is a first step needed towards being able to asynchronously
populate assist data.

Previously content changes were only handled if they came directly from
the focused host, which meant that changes that occurred higher in the
tree were ignored. As a result, scrolling in ViewPager that contained
virtual nodes would fail to update the focus position.

If a user drags with a stylus (or mouse) across the screen with
the stylus primary (or mouse secondary) button clicked, this will
initiate a scale gesture that functions similarly to the quick
scale gesture: drag below starting point zooms in, drag above
starting point zooms out.
Combines some of the logic for quick scale and button
scale due to similarities.

When the View opens the context menu, the mouse-down event is
already handled. Therefore, the next ACTION_UP should be canceled,
otherwise, single right click shows the context menu and then
invokes the normal click actions.
Also, the right-down event should always be consumed regardless
of the context menu support. "the right click opens the context
menu on some views, but it behaves as a normal click on some
other views" would confuse users.

This will allow any View to include foreground drawables. This is
useful for cases where a foreground drawable is a more appropriate
place to put a state list to show focus or touch highlighting.
Also add View#onDrawForeground as a public API hook for drawing
decorations after primary view content and child views such as
scrollbars, foreground drawables and EdgeEffects.
