The key thing was to fix isVisibleOrBehindKeyguardLw() so that it
wouldn't count a window as not visible if it was just currently
in the process of drawing due to an orientation change.
Also improve logic in deciding when to turn screen on to better ensure
the screen is in a stable state, in particular treating screen off
as a frozen screen and not allowing it to turn on until the
update of the screen due to any config change is done.

Rework how we decide when it is okay to turn on the screen by having

PhoneWindowManager now takes full responsibility for deciding where the
navigation bar goes. This gets rid of a bunch of race conditions with
determining layout while the nav bar is moving itself at the same time
the window manager is computing a new configuration.
Note that this breaks the "nav bar on left" option. The current nav
bar code could also be cleaned up some more to completely drive its
behavior based on onSizeChanged() happening during relayout.

Bug: 5156144
Input channels could leak or simply live longer than they should
in some cases.
1. Monitor channels (used by the pointer location overlay) are never
unregistered, so they would leak.
Added code to handle failures in the receive callback by closing
the input channel.
2. The DragState held onto its input window and application handles
even after the input channel was disposed.
Added code to null these handles out when they are no longer needed.
3. Input channels previously used as input event targets would stick
around until the targets were cleared (usually on the next
event).
Added code to detect when the input dispatcher is in
an idle state and to proactively clear the targets then
to ensure that resources are released promptly.
4. Native input window handles held onto the input channel even
after the input window was removed from the input dispatcher.
Consequently, the input channel would not be disposed until
the input window handle itself was freed. Since the input
window handle is held from managed code, this meant that the
window's input channel could stick around until the next GC.
Refactored the input window handle to separate the properties
(info) and identify (handle) state into different objects.
Then modified the dispatcher to release the properties (info)
when no longer needed, including the input channel.
7. The pointer location overlay does not actually use its
standard input channel, only the monitor input channel.
Added INPUT_FEATURE_NO_INPUT_CHANNEL to allow windows to
request that they not be provided with an input channel
at all.
Improved some of the error handling logic to emit the status
code as part of the exception message.

There turn out to be two distinct bugs leading to runtime restarts.
The first, dating from at least Android 3.1, is that following certain kinds
of app crashes we properly clean up the drag-state bookkeeping, but aren't
prepared in the case of the drag-target timeout clock firing with a now-
null drag state in effect. We now catch that edge condition and don't NPE
(and note that there was already similar code around the separate timeout
when an app is *starting* the drag process).
The second bug is that some new-in-ICS code in the input channel management
wasn't prepared for certain cases where the current touch window could have
become unusable and its input channel torn down summarily in the case of the
aforesaid app crash during drag. The code now makes sure that there really
is an input channel that needs to be flushed / cancelled prior to attempting
that operation.

The activity manager now take care of plugging the correct settings
into the OOM killer in the kernel. This is a lot cleaner because
it is really central to how the activity manager works, and nobody
else cares about them.
Taking advantage of this, the activity manager computes what it
thinks are appropriate OOM levels based on the RAM and display
size of the device.
Also a small optization to the package manager to keep a binding
to the package install helper for a bit after done using it, to
avoid thrashing on it.
And some new APIs that are now needed by Settings.

The input reader needs this information so that it knows how to
interpolate touches on an external touch screen.
Changed Display so that it asks the WindowManager what the real
display size is (as opposed to the raw display size). This means
it now takes into the forced display size set by
adb shell am display-size.
Replaced all calls to getRealWidth() / getRealHeight() /
getRealMetrics() in the WindowManager and replaced them with direct
usages of the mCurDisplayWidth / mCurDisplayHeight so that the WM
doesn't end up making a reentrant Binder call into itself.
Fixed the table status bar HeightReceiver so that it updates the
height on all configuration changes since it is possible that the
display size changed independently of an external HDMI display
being plugged / unplugged.
Improved the Display class documentation to make the distinctions
betweeen the various sizes clearer.

This change moves the cached window and application input state
into the handle objects themselves. It simplifies the dispatcher
somewhat because it no longer needs to fix up references to
transient InputWindow objects each time the window list is updated.
This change will also make it easier to optimize setInputWindows
to avoid doing a lot of redundant data copying. In principle, only
the modified fields need to be updated. However, for now we
continue to update all fields in unison as before.
It turns out that the input dispatcher was inappropriately retaining
pointers to InputWindow objects within the mWindows InputWindow
vector. This vector is copy-on-write so it is possible and the
item pointers to change if an editing operation is performed on
the vector when it does not exclusively own the underlying
SharedBuffer. This bug was uncovered by a previous change that
replaced calls to clear() and appendVector() with a simple use
of operator= which caused the buffer to be shared. Consequently
after editItemAt was called (which it shouldn't have, actually)
the buffer was copied and the cached InputWindow pointers became
invalid. Oops. This change fixes the problem.
