We need to work more like before in determining whether the menu
key is needed -- in some cases look back in the window list to
determine this if we don't know the value from the current window.
This requires adding a new private flag indicating whether the
compat menu state is known for a window, which is set by
PhoneWindow as part of its existing process of computing the flag
for its own windows.
Now we can have a new API on WindowState to determine the value
of this flag for a window, which if needed walks back in the window list
to find a window the value is known for (or stops at what the policy
has determined is the top full-screen window, so we stop like we used
to at things like the lock screen or the bottom of an application).

Make surface management between SurfaceView and the window manager
much more controlled, to ensure that SurfaceView always gets to report
the current surface is destroyed before the window manager actually
destroys it.
Also a small tweak to allow windows that have a wallpaper background
to still have a preview window. This makes launching home after it
has been killed feel much more responsive.

Introduce a new concept of "B" services. All running services are
classified as either A or B. B services are later in the LRU list.
Their oom_adj is after the home app. This allows us to better pick
services to kill based on how long they have running, and should
reduce the amount that we end up killing the home app.
This temporarly turns on a debug log when the oom_adj of a process
is changed. Sorry, I know it is noisy. This is needed to try to
track down why some processes are being killed.
Also add a flag to the SyncManager's service binding to allow the
syncing process to be more aggressively killed if it has done UI.
This is to address cases we have seen where sync is causing an 80MB
gmail process to be kept around, preventing other process from running.
Now what will happen is that the syncing process will aggressively be
killed by the system, and can then be restarted in a much lighter-weight
state.
Do a little tweak in the power manager to allow us to still do smooth
brightness changes even when the fancy TV off animation is in use.
And get rid of a debug log in the window manager that was accidentally
left in.

Fix a few places where we would unfreeze the screen too early.
Now that we are no longer relying on surface flinger freezing, we
can't depend on it keeping the screen frozen until surfaces get
drawn.

The window manager now uses the app screen dimensions to compute
the various configuration properties, as it should.
This means that prime is official a "not long" device. Poor prime.
It probably feels inadequate now.
Because it is.
Oh and all that other stuff? Debugging logs. Turned off. And
why the heck not, debugging logs are great.

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.

This change ensures the wallpaper is rendered into an opaque surface
which avoids a glClear() in SurfaceFlinger. This should save quite
a bit of work on every frame when panning the workspace in launcher.

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.

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.

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.

...for Market App iRunner
There were a lot of serious issues with how we updated (or often didn't update)
the display and resource state when switching compatibility mode in conjunction
with restarting and updating application components. This addresses everything
I could find.
Unfortunately it does *not* fix this particular app. I am starting to think this
is just an issue in the app. This change does fix a number of other problems
I could repro, such as switching the compatibility mode of an IME.
Also a few changes here and there to get rid of $#*&^!! debug logs.

Rip out the old funky code for trying to restrict the app window
sizes to be within the compat mode range. Instead, we know rely
entirely on scaling -- we deal with windows always with the scaling
applied so that the window manager doesn't have to deal with them
specially. Instead, we just apply the inverse scale at the few
points we need to do something the app sees.

Applications now get the display size from the window manager. No
behavior should be changed yet, this is just prep for some real
changes.

First step of improving app screen size compatibility mode. When
running in compat mode, an application's windows are scaled up on
the screen rather than being small with 1:1 pixels.
Currently we scale the application to fill the entire screen, so
don't use an even pixel scaling. Though this may have some
negative impact on the appearance (it looks okay to me), it has a
big benefit of allowing us to now treat these apps as normal
full-screens apps and do the normal transition animations as you
move in and out and around in them.
This introduces fun stuff in the input system to take care of
modifying pointer coordinates to account for the app window
surface scaling. The input dispatcher is told about the scale
that is being applied to each window and, when there is one,
adjusts pointer events appropriately as they are being sent
to the transport.
Also modified is CompatibilityInfo, which has been greatly
simplified to not be so insane and incomprehendible. It is
now simple -- when constructed it determines if the given app
is compatible with the current screen size and density, and
that is that.
There are new APIs on ActivityManagerService to put applications
that we would traditionally consider compatible with larger screens
in compatibility mode. This is the start of a facility to have
a UI affordance for a user to switch apps in and out of
compatibility.
To test switching of modes, there is a new variation of the "am"
command to do this: am screen-compat [on|off] [package]
This mode switching has the fundamentals of restarting activities
when it is changed, though the state still needs to be persisted
and the overall mode switch cleaned up.
For the few small apps I have tested, things mostly seem to be
working well. I know of one problem with the text selection
handles being drawn at the wrong position because at some point
the window offset is being scaled incorrectly. There are
probably other similar issues around the interaction between
two windows because the different window coordinate spaces are
done in a hacky way instead of being formally integrated into
the window manager layout process.
