The DIRTY flag is used to track which elements of the view hierarchy need
to be redrawn on the next drawing operation. This flag is set on the parent
hierarchy of a view when that view is invalidated. There is an optimization for
opaque views that tells the parent that it is dirty, but that it need not
redraw its own content because the view will cover it (since it is opaque).
This dirty-opaque logic breaks down in the current code because we only set
these dirty flags on the parent hierarchy, not on the view itself. In the situation
raised by this bug, we would invalidate the parent container directly (which does
not case the dirty flag to be set), then we would invalidate a child of that view.
Because the child is opaque, the DIRTY_OPAQUE flag would be set on the parent
container. This would cause us, in the later rendering process, to skip the
drawing on that parent container, assuming that it was only asked to be redrawn
because of its opaque child's invalidation.
The fix is to now set the DIRTY flag on an invalidated view, not just on its parent
hierarchy. The DIRTY_OPAQUE logic will avoid setting the opaque flag on views/parents
that are already marked DIRTY, thus an invalidated parent will be correctly drawn
during the drawing process.

1. There was a bug that was not handling correctly the
case for which the interrogator requests an accessibility
node info and the message describing how to fetch the
latter for the same process case was delivered after the
code that checks whether the message is there in order to
dispatch it is executed. Now the message handling is done
correctly - the caller checks if the message is present and
if so processes it, otherwise the caller sleeps and is
interrupted if such a message arrives.

1. Some invisible views' text was reported by accessibility events.
2. Accessibility actions could have been perfromed on invisible views.

This new hidden API is called by ViewRootImpl when there is a pending
transition but the parent window is not visible.

There's a problem with how LayoutTransition cleans up after itself
when the target view is in a Window that is not on the screen.
The quick fix is to always start (and therefore properly end and clear)
transitions, regardless of whether the window is in the tree.

Two problems fixed here:
- The docs for AnimationSet were too vague and incorrect: some properties of
Animation (such as duration) are pushed from the AnimationSet down to its children, as
the current docs say. Some other properties (such as repeatCount) are ignored. Other
properties (such as startOffset) apply to the Set itself, but not to the children.
Fix: clarify this behavior for each of the properties.
- The behavior for XML resources was just busted. We would set the various properties
(e.g., duration) and then forget that we did so, since we reset the flags that marked
their existence after we loaded the resource. In fact, the duration property was
always being reset to 0, regardless of what it was set to in the xml resource.
Fix: Make it work they way it always should have: respect the values read from the XML
resource and make them behave the same way they do when set at runtime.

Logic in performTraversals() starts a transition running at the
proper time. But when a view's parent window goes away, this transition
may not start at that time because drawing gets canceled. But the
transition still hung off of the ViewRoot, waiting until some later
drawing operation to kick it off. This resulted in some weird animations
like the Recents panel appearing and having a single item animate off of it.
The fix is to delete pending transitions when drawing is skipped.

...opening after selecting option "Youtube" as a luncher.
Also:
* Tweak window animations so that the wallpaper exist animations do not
stop too early (causing the wallpaper to suddenly disappear).
* Make sure no input is being processed while booting, to avoid
accidentally doing things especially in the upgrade dialog.
* Some other small cleanup.

1. Added a check whether the received hover event is in the bounds
if the view before sending accessiiblity hover events. Hence, if
a widnow gets a hover event and it gets to its topmost view the
latter will not fire an accessibility event.
