This cleans up how ui flags are managed between the client and window manager.
It still reports the global UI mode state to the callback, but we now only clear
certain flags when the system goes out of a state (currently this just means the
hide nav bar mode), and don't corrupt other flags in the application when the
global state changes.
Also introduces a sequence number between the app and window manager, to avoid
using bad old data coming from the app during these transitions.

Bug: 4981385
Changed the orientation listener to notify the policy whenever
its proposed orientation changes, and changes the window manager
to notify the orientation listener when the actual orientation
changes. This allows us to better handle the case where the
policy has rejected a given proposal at one time (because the
current application forced orientation) but might choose
to accept the same proposal at another time.
It's important that the proposal always be up to date. A proposal
becomes irrelevant as soon as the phone posture changes such
that we can no longer determine the orientation with confidence
(such as when a device is placed flat on a table).
Simplified the orientation filtering. Now we just wait 200ms
for the device to be still before issuing a proposal. The idea
is that if the device is moving around a lot, we assume that
the device is being picked up or put down or otherwise in
the process of being moved. We don't want to change the rotation
until that's all settled down. However, we do want to tolerate
a certain amount of environmental noise.
(The previous confidence algorithm was also designed along
these lines but it was less direct about waiting for things
to settle. Instead it simply made orientation changes take
longer than usual while unsettled, but the extra delay was often
too much or too little. This one should be easier to tune.)

Bug: 4981385
Simplify the orientation changing code path in the
WindowManager. Instead of the policy calling setRotation()
when the sensor determined orientation changes, it calls
updateRotation(), which figures everything out. For the most
part, the rotation actually passed to setRotation() was
more or less ignored and just added confusion, particularly
when handling deferred orientation changes.
Ensure that 180 degree rotations are disallowed even when
the application specifies SCREEN_ORIENTATION_SENSOR_*.
These rotations are only enabled when docked upside-down for
some reason or when the application specifies
SCREEN_ORIENTATION_FULL_SENSOR.
Ensure that special modes like HDMI connected, lid switch,
dock and rotation lock all cause the sensor to be ignored
even when the application asks for sensor-based orientation
changes. The sensor is not relevant in these modes because
some external factor (or the user) is determining the
preferred rotation.
Currently, applications can still override the preferred
rotation even when there are special modes in play that
might say otherwise. We could tweak this so that some
special modes trump application choices completely
(resulting in a letter-boxed application, perhaps).
I tested this sort of tweak (not included in the patch)
and it seems to work fine, including transitions between
applications with varying orientation.
Delete dead code related to animFlags.
Handle pausing/resuming orientation changes more precisely.
Ensure that a deferred orientation change is performed when
a drag completes, even if endDragLw() is not called because the
drag was aborted before the drop happened. We pause
the orientation change in register() and resume in unregister()
because those methods appear to always be called as needed.

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 input reader needs this information so that it knows how to

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.
