This is used to allow list view's pressed and activated indicators
to fade in an out, though of course it can be used elsewhere as well.
There is a lot of complexity in supporting this in list view. The
two main things that are being dealt with:
- When recycling views, we need to make sure that the view's drawable
state doesn't get animated from an old row's state. The recycler
now keeps track of which position a view was last in, and if it is
reused at a new position there is a new View/Drawable API to tell
it to jump to its current state instead of animating.
- For the pressed indicator to fade out, we need to keep displaying it
after it is hidden. There are new variables and code to keep track
of this state, and tweaks in various places to be able to remember
the last selected position and continue updating the drawable bounds
as needed.

The animator classes caused autoboxing by converting primitive types (by far
the most typical types used in animations) to be converted to their
Object equivalents because of various APIs that required Object
(like getValue() to get the animated value). This change creates
factory methods on some classes instead of the former constructors
so that we can create and return private type-specific subclasses
which operate directly on the primitive types instead.
In particular, float and int are natively supported by the animators
now. Support in the APIs for double and long was removed because it
seemed like these less common types did not justify the extra
baggage of the added API and code.

Now, each ViewGroup is tracking which of its child views [which might
themselves be ViewGroups] is currently under the drag point, and when the
drag leaves that child, a DRAG_EXITED is synthesized and dispatched all
the way down to the leaf view previously under the point. ENTERED is
still *not* dispatched down like this; instead, it's calculated and
synthesized directly at each level based on the new LOCATION.
The ViewRoot still tracks the leaf drag target, but solely for the
purpose of reporting changes to the OS after full dispatch of a new
LOCATION -- the entered/exited messaging is no longer initiated at the
ViewRoot level.

Rewrote interceptKeyBeforeQueueing to make the handling more systematic.
Behavior should be identical except:
- We never pass keys to applications when the screen is off and the keyguard
is not showing (the proximity sensor turned off the screen).
Previously we passed all non-wake keys through in this case which
caused a bug on Crespo where the screen would come back on if a soft key
was held at the time of power off because the resulting key up event
would sneak in just before the keyguard was shown. It would then be
passed through to the dispatcher which would poke user activity and
wake up the screen.
- We propagate the key flags when broadcasting media keys which
ensures that recipients can tell when the key is canceled.
- We ignore endcall or power if canceled (shouldn't happen anyways).
Changed the input dispatcher to not poke user activity for canceled
events since they are synthetic and should not wake the device.
Changed the lock screen so that it does not poke the wake lock when the
grab handle is released. This fixes a bug where the screen would come
back on immediately if the power went off while the user was holding
one of the grab handles because the sliding tab would receive an up
event after screen turned off and release the grab handles.
Fixed a couple of issues where media keys were being handled inconsistently
or not at all, particularly in the case of the new PAUSE, PLAY
and RECORD keys.

DragEvent.getResult() returns 'true' if the drop was ultimately accepted;
false otherwise. The validity of this datum is only guaranteed when the
DragEvent's action verb is ACTION_DRAG_ENDED.
Also fixes the drag-start timeout handling (though the offending app is
not yet officially declared ANR).

If the listener's onDrag(view, event) returns 'false', the view's own
onDragEvent() will be called. If the listener returns 'true', it
consumes the event (and declares that it will handle the rest of the
drag event sequence, in the case of DRAG_STARTED actions).

Manual merge from Gingerbread.
This change adds a new window type for secure system overlays
created by the system itself from non-secure system overlays that
might be created by applications that have the system alert permission.
Secure views ignore the presence of secure system overlays.

Change-Id: Id876736fd8bf332ff9a5428bde59f5268aa49c3a
Added new key maps for external keyboards. These maps are intended to
be shared across devices by inheriting the "keyboards.mk" product
makefile as part of the device's product definition.
One of the trickier changes here was to unwind some code in
MetaKeyKeyListener that assumed that only the low 8 bits of the meta key
state were actually used. The new code abandons bitshifts in favor
of simple conditionals that are probably easier to read anyways.
The special meta key state constants used by MetaKeyKeyListener
are now (@hide) defined in KeyEvent now so as to make it clearer that they
share the same code space even if those codes are not valid for KeyEvents.
The EventHub now takes care of detecting the appropriate key layout
map and key character map when the device is added and sets system
properties accordingly. This avoids having duplicate code in
KeyCharacterMap to probe for the appropriate key character map
although the current probing mechanism has been preserved for legacy
reasons just in case.
Added support for tracking caps lock, num lock and scroll lock and
turning their corresponding LEDs on and off as needed.
The key character map format will need to be updated to correctly support
PC style external keyboard semantics related to modifier keys.
That will come in a later change so caps lock doesn't actually do
anything right now except turn the shiny LEDs on and off...
Added a list of symbolic key names to KeyEvent and improved the toString()
output for debug diagnosis. Having this list in a central place in the
framework also allows us to remove it from Monkey so there is one less
thing to maintain when we add new keycodes.

* Properly wipe the thumbnail canvas before handing it to the app for
its contents to be drawn
* Provide a getView() method in DragThumbnailBuilder that allows
clients or subclasses to get at the associated view. This is
especially for clients that want to draw entire (sub)layouts as
the drag thumbnail, by overriding onDrawThumbnail(Canvas c)
like this:
// Override specifically for drawing a whole ViewGroup into
// the drag thumbnail canvas
@Override
public void onDrawThumbnail(Canvas c) {
getView().dispatchDraw(c);
}

Windows with FLAG_NEEDS_MENU_KEY (or windowNeedsMenuKey=true
in their theme) will cause the system bar to show a menu
icon. (Note that the phone's status bar currently ignores
this, but phones tend to have hardware menu keys anyway.)
Additionally, all windows whose package's SDK version is
pre-Honeycomb will have FLAG_NEEDS_MENU_KEY set by default.

The recipient app could be receiving drag location updates faster than
it handled them, leading to progressive poor responsiveness. Now we
discard any undelivered pending location updates and replace them with
the newest data point when the location is updated.

Bug #3081600
The OpenGL renderer in libhwui uses a single EGL context per process and
thus create it with an RGBA 8888 EGL configuration. To ensure that all
windows are compatible with this configuration, this change modifies
the window manager and SurfaceFlinger.
The window manager now checks the window's flags and if the window is
hardware accelerated, it forces the window's pixel format to be
translucent when creating the surface. The window itself is still
marked as opaque if we know that the window will be opaque on screen.
This keeps existing optimizations in place.
Similarly in SurfaceFlinger, a translucent Surface can now be created
with the Surface.OPAQUE flag, indicating SurfaceFlinger that the surface
does not require blending, despite its RGBA 8888 configuration.

Added the concept of a "trusted" event to distinguish between events from
attached input devices or trusted injectors vs. other applications.
This change enables us to move certain policy decisions out of the
dispatcher and into the policy itself where they can be handled more
systematically.

Merge commit '1e6a3a53fc4d56e3a0f86c8721dedfd46e738a32' into gingerbread-plus-aosp
* commit '1e6a3a53fc4d56e3a0f86c8721dedfd46e738a32':
Added more robust tracking and cancelation of events.
This change fixes several issues where events would be dropped in the
input dispatch pipeline in such a way that the dispatcher could not
accurately track the state of the input device.
Given more robust tracking, we can now also provide robust cancelation
of input events in cases where an application might otherwise become
out of sync with the event stream due to ANR, app switch, policy decisions,
or forced focus transitions.
Pruned some of the input dispatcher log output.
Moved the responsibility for calling intercept*BeforeQueueing into
the input dispatcher instead of the input reader and added support for
early interception of injected events for events coming from trusted
sources. This enables behaviors like injection of media keys while
the screen is off, haptic feedback of injected virtual keys, so injected
events become more "first class" in a way.
