In particular, if a new window was created out from under the drag,
the drag-move event dispatch logic would wind up blithly assuming
that it would find a valid touch-dispatchable window under the
finger. When this was untrue, it would NPE, but the NPE was caught
and discarded safely by higher-level guard code.
With this change, we now avoid the NPE entirely and report the
spurious condition as part of the debugging log stream.
(Also add the local-state object to DragEvent.toString()'s output.)

Bug 3347962
Root cause of this problem: if the adapter's content gets updated by a backgroung
thread, the PopupDataSetObserver will call showDropDown which will popup the
list.
Added a flag to make this call show the popup iif it is already visible.
This relayout is needed to clear the mDataChanged flag set when the content was
modified and which otherwise prevents touch events on the result list.
ArrayAdapter didn't use its lock to protect access to mObject.
-------------------------------------------------
However, the study of the this race conditions revealed an other bug:
Updated adapter's content is not displayed in filtered AutoCompleteTextView

1. ViewGroups being removed from the layout during a drag would wind up
crashing the app with an NPE at drag-ended time, due to blind dereference
of now-cleared object pointers.
2. Passing a 'null' ClipData to startDrag() would crash the system
process with an NPE. Should this even be valid? I'm inclined to say
yes, though it means that apps will need to guard against it.

When the AudioFlinger runs out of available AudioTracks (max 32),
the ToneGenerator constructor throws a RuntimeException. Although this
denotes an abnormal situation, VolumePanel should catch this exception.

Don't dismiss by default when tapping outside, even for AlertDialog.
If AlertDialog doesn't have any buttons, tapping outside will dismiss it.
Applications can make their own dialogs (or activities looking like
dialogs) can use the existing and new APIs to control this behavior
themselves so that it does the right thing.

This enables the system bar to carve out a region through which
events will be sent to the IME behind it.

Added check avoid a division by zero resulting in NaN which in turn
makes checkFullyTilted to ignore high tilt angles from then on.
If (x, y, z) == (0, 0, 0) then there is no tilt or rotation and
this vector must be ignored. This check is extended to ignore all
small acceleration values where noise can be of big influence.
Low or zero readings can happen when space travelling free falling,
but more commonly when shaking or getting bad readings from the sensor.
The accelerometer is turned off when not used and polling it too soon
after it is turned on may result in (0, 0, 0).

We now recognize that a view is now a candidate for receiving the drop
but hasn't yet been notified about it, and send the DRAG_STARTED lifecycle
event properly. This change also changes the DRAG_ENDED policy: now,
every view that had been sent a DRAG_STARTED receives the corresponding
DRAG_ENDED event, even though subsequent visibility changes may have
occured.

The problem is that if a window containing children is removed
before the children are, the children may be lost. This change
(amongst the huge amount of new debugging code) now ensures at
this point that all children windows are removed when the parent
is.
Note that this results in a bunch of error messages now as the
client app tries to continue to do things with that child window.
This is correct, it shouldn't be doing that, and needs to be
fixed to stop it. But at least it now can't cause the window
manager to leak surfaces.

The new implementation relies on OpenGLRenderer's existing layer
code instead of duplicating it. The new code is much cleaner, with
simpler and better APIs and allows tracking of drawn regions inside
layers. Region tracking is not yet enabled but this will be done
in a future CL.

LayoutTransition works by animating layout-related properties
(left, right, top, and bottom). This works great when that animation
is the only thing affecting the layout of the UI. But if there are other things
happening in the application that cause layout to run on that
container or in its parent hierarchy, this can cause the layout properties
on its children to get mis-set during the middle of the transition.
This results in artifacts like animating objects jumping to locations where
they would be were there no animation running.
The fix is to supress layout requests on that container (and its children)
until the transition is complete (then issue a layout request on the container
to make sure that the container has the correct layout data)

There will be, in the future, a flag (View.DRAG_FLAG_GLOBAL) that means
for the drag to be cross-application. For now that flag constant is @hide
and furthermore the server-side implementation strips it, enforcing
local-only drags.
