The goal is to fix a bunch of fragment-related bugs caused by various
things trying to do fragment transactions after onPause()... which
currently throws an exception, since this is after the activity's state
has been saved so the new fragment state can be lost.
The basic change is relatively simple -- we now consider processes
hosting paused or stopping activities to be unkillable, and the client
code now does the onSaveInstanceState() as part of stopping the
activity.
For compatibility, if an app's targetSdkVersion is < HONEYCOMB, the
client side will still call onSaveInstanceState() prior to onPause()
and just hold on to that state until it needs to report it in once
being stopped.
Also included here is a change to generate thumbnails by taking
screenshots. The code for generating thumbnails by re-rendering
the view hierarchy is thus removed.

This change enables the framework to synthesize key events to implement
default behavior when an application does not handle a key.
For example, this change enables numeric keypad keys to perform
their associated special function when numlock is off.
The application is informed that it is processing a fallback keypress
so it can choose to ignore it.
Added a new keycode for switching applications.
Added ALT key deadkeys.
New default key mappings:
- ESC -> BACK
- Meta+ESC -> HOME
- Alt+ESC -> MENU
- Meta+Space -> SEARCH
- Meta+Tab -> APP_SWITCH
Fixed some comments.
Fixed some tests.

This patch allows users of WindowManagerService.injectKeyEvent() to
set flags on the key event being injected.
In particular this allows long presses (FLAG_LONG_PRESS) to be
injected into the window manager.
When calling startDrag(), the app can now supply an Object to be passed
along in every DragEvent that the app winds up receiving itself. This
object is *not* passed to any other applications; it's strictly app-
local. The purpose is to allow state tracking/management to be done
directly through the drag mechanism rather than requiring out-of-band
code.
An example of the utility here might be TextEdit widgets. A drag that
starts in one TextEdit but ends in a different one should be treated as
a copy/paste operation, where the originating TextEdit is not altered.
However, a drag that starts and ends in the *same* TextEdit is a 'move'
operation within that TextEdit; the text is removed from its original
position and inserted at the drop point. To support this easily, the
drag/drop code in TextEdit can now pass a pointer to the originating
view as the local state object. Then, the drop recipient could tell
whether the drag started within the same TextEdit without needing to
implement any other out-of-band state tracking.
This CL (and its accompanying CLs in a few other packages where the
startDrag() API is being used) adds the new local-state parameter to
the API, but does not actually change the behavior of any existing
clients.

ViewRoot now does a fade animation between a snapshot of the previous
layout to the new one when its content rect changes.
Also tweaked some things in the window manager to fix problems in

The ShortcutManager used to only receive the key code of the key event
that triggered the shortcut. This change now provides the shortcut
manager with the whole key event so it can look up the associated
character using the correct key character map.
To make this more efficient, added a mechanism for recycling
key events. At the moment it is only used by key events owned by the
system process, since clients of the existing API (such as Views)
might continue to hold on to key events after dispatch has finished so
they would break if the key event were recycled by the framework.
Deprecated KeyCharacterMap.BUILT_IN_KEYBOARD.

This introduces a small new feature for ScaleAnimation allowing
the scaling factor to be expressed as a percentage of the object
(which is the same as the existing float interpretation), a
percentage of the container, or a fixed dimension. Maybe not
useful for anything else, but I needed it for this.
Also fix a bug in how transformation matrices were propagated
from the Animation to Surface Flinger, so that rotate and skew
animations will actually work. :p

We now decide whether to use a bitmap background based on whether the
window's drawing is hardware accelerated. To do this, there is a new
"state_accelerated" that state list drawables can be parameterized on,
and the standard window background uses this to select a solid color
or bitmap drawable as appropriate.
Introduces a little hackery to have wm preview windows pretend like
they are hardware accelerated even if they aren't, so the preview looks
closer to the actual app.
Also Add a DialogWhenLarge variation for the light theme.

IWindowManager now supports two new methods,
freezeRotation() and thawRotation(), that allow a caller to
temporarily stash the device's current rotation as the
default rotation (when no other constraints are present).
The system bar uses this to implement a user-accessible
rotation lock by calling freezeRotation() and then turning
off accelerometer-based display rotation; unless overridden
by an app, the display will continue to appear in the frozen
rotation until the rotation is unlocked by the user (either
via the rotation lock icon in the system bar or by checking
"rotate screen automatically" in Settings).

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.

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.

Thumbnail measurement & drawing has been moved out into a delegate
class called View.DragThumbnailBuilder. This consolidates the
thumbnail-related code as well as ensuring that the drag initiator
does not have to know a priori where to place the thumbnail relative
to the touch point *before* the thumbnail measurement step, as was
previously the case.
startDrag() no longer needs to be told where the current touch point
is at the time the drag is launched.
Drag events are now dispatched only to VISIBLE views.
Dispatch shouldn't double-recycle events any more when the target
window is local to the system process.
