blank() and unblank() now take a display argument. For now,
just pass the default display in.

To encourage vendors to make power on/off as efficient
and responsive as possible, we log some warnings whenever it
is too slow. The previous thresholds were a little
unreasonable mainly because we wanted to understand
how long the process tends to take even when it's fast.
Raise the warning limit while still being aggressive about
timings. Ideally we want the screen to turn on/off within
no more than a few frames.

The input system needs to know about the window that has
focus, even if it is on a secondary display. So now we
send it the list of all windows and indicate which display
they are on. We filter the list of windows as necessary
when delivering touch events.
To keep things simple, monitor input channels and input
filters are not supported except on the main display.
We also do not pass the display id to applications; it is
only used inside the input system for now.
Properly scale touch coordinates based on the viewport.
This will be needed to ensure that touch works on external
display as well as when the internal display is being used
to simulate a different resolution.

Cleaned up the implementation of Surface and SurfaceSession
to use more consistent naming and structure.
Added JNI for all of the new surface flinger display API calls.
Enforced the requirement that all Surfaces created by
the window manager be named.
Updated the display manager service to use the new methods.

The major goal of this rewrite is to make it easier to implement
power management policies correctly. According, the new
implementation primarily uses state-based rather than event-based
triggers for applying changes to the current power state.
For example, when an application requests that the proximity
sensor be used to manage the screen state (by way of a wake lock),
the power manager makes note of the fact that the set of
wake locks changed. Then it executes a common update function
that recalculates the entire state, first looking at wake locks,
then considering user activity, and eventually determining whether
the screen should be turned on or off. At this point it may
make a request to a component called the DisplayPowerController
to asynchronously update the display's powe state. Likewise,
DisplayPowerController makes note of the updated power request
and schedules its own update function to figure out what needs
to be changed.
The big benefit of this approach is that it's easy to mutate
multiple properties of the power state simultaneously then
apply their joint effects together all at once. Transitions
between states are detected and resolved by the update in
a consistent manner.
The new power manager service has is implemented as a set of
loosely coupled components. For the most part, information
only flows one way through these components (by issuing a
request to that component) although some components support
sending a message back to indicate when the work has been
completed. For example, the DisplayPowerController posts
a callback runnable asynchronously to tell the PowerManagerService
when the display is ready. An important feature of this
approach is that each component neatly encapsulates its
state and maintains its own invariants. Moreover, we do
not need to worry about deadlocks or awkward mutual exclusion
semantics because most of the requests are asynchronous.
The benefits of this design are especially apparent in
the implementation of the screen on / off and brightness
control animations which are able to take advantage of
framework features like properties, ObjectAnimator
and Choreographer.
The screen on / off animation is now the responsibility
of the power manager (instead of surface flinger). This change
makes it much easier to ensure that the animation is properly
coordinated with other power state changes and eliminates
the cause of race conditions in the older implementation.
The because of the userActivity() function has been changed
so that it never wakes the device from sleep. This change
removes ambiguity around forcing or disabling user activity
for various purposes. To wake the device, use wakeUp().
To put it to sleep, use goToSleep(). Simple.
The power manager service interface and API has been significantly
simplified and consolidated. Also fixed some inconsistencies
related to how the minimum and maximum screen brightness setting
was presented in brightness control widgets and enforced behind
the scenes.
At present the following features are implemented:
- Wake locks.
- User activity.
- Wake up / go to sleep.
- Power state broadcasts.
- Battery stats and event log notifications.
- Dreams.
- Proximity screen off.
- Animated screen on / off transitions.
- Auto-dimming.
- Auto-brightness control for the screen backlight with
different timeouts for ramping up versus ramping down.
- Auto-on when plugged or unplugged.
- Stay on when plugged.
- Device administration maximum user activity timeout.
- Application controlled brightness via window manager.
The following features are not yet implemented:
- Reduced user activity timeout for the key guard.
- Reduced user activity timeout for the phone application.
- Coordinating screen on barriers with the window manager.
- Preventing auto-rotation during power state changes.
- Auto-brightness adjustment setting (feature was disabled
in previous version of the power manager service pending
an improved UI design so leaving it out for now).
- Interpolated brightness control (a proposed new scheme
for more compactly specifying auto-brightness levels
in config.xml).
- Button / keyboard backlight control.
- Change window manager to associated WorkSource with
KEEP_SCREEN_ON_FLAG wake lock instead of talking
directly to the battery stats service.
- Optionally support animating screen brightness when
turning on/off instead of playing electron beam animation
(config_animateScreenLights).

This puts in most of the infrastructure needed to allow us to
switch between different densities at run time. The main remaining
uses of the global are to initialize the Bitmap object (not sure
what to do about that since it doesn't have anything passed in
the constructor to get this information from), and being able to
load drawables if we need a different density than what was preloaded
by zygote.

The purpose of this change is to remove direct reliance on
SurfaceFlinger for describing the size and characteristics of
displays.
This patch also starts to make a distinction between logical displays
and physical display devices. Currently, the window manager owns
the concept of a logical display whereas the new display
manager owns the concept of a physical display device.

This refactoring sets the stage for a follow-on change that
will make use additional functions of the power HAL.
Moved functionality from android.os.Power into PowerManagerService.
None of these functions make sense being called outside of the
system server. Moving them to the PowerManagerService makes it
easier to ensure that the power HAL is initialized exactly once.
Similarly, moved ShutdownThread out of the policy package and into
the services package where it can tie into the PowerManagerService
as needed.

When attached to an HDMI touch screen, the input system needs
to know the size and rotation of the external display independent
of the internal display. The size was already being reported
separately but not the rotation. The inconsistency can cause problems
if the internal display's natural rotation is portrait but
the external display's natural rotation is landscape.

The window manager policy made some incorrect assumptions about the
meaning of the Configuration.keyboard field. We need to be more
careful about distinguishing between built-in and external keyboards.
Most of this change is to move the determination of the parts of
the Configuration related to input devices into the WindowManagerService
leveraging new features of the InputManagerService to good effect.
Then we plumb through the flag that indicates whether a device
is internal or external so that we can be more particular about
how the lid switch effects changes to the Configuration.

Bluetooth devices can be renamed by the user. Make the
input system aware of the user-specified name and transparently
pass it down to applications. This enables the keyboard
layout picker Settings UI to use device names that are

Added the concept of a keyboard layout overlay, which is
a key character map file that has "type OVERLAY".
Added support for loading keyboard layout overlays from
resources dynamically. The layouts are reloaded whenever they
are changed in the Settings application or an application
is installed. This is somewhat more aggressive than necessary
so we might want to optimize it later.
Before system-ready, the input system uses just the generic
keyboard layouts that are included on the device system image.
After system-ready, it considers the user's selected keyboard
layout overlay and attempts to load it as necessary. We need to
wait until system-ready before doing this because we need to
be in a state where it is safe to start applications or access
their resources.

This change allows the InputManager to keep track of what input
devices are registered with the system and when they change.
It needs to do this so that it can properly clear its cache of
input device properties (especially the key map!) when changes
occur.
Added new API so that applications can register listeners for
input device changes.
Fixed a minor bug in EventHub where it didn't handle EPOLLHUP
properly so it would spam the log about unsupposed epoll events
until inotify noticed that the device was gone and removed it.

Instead of each application loading the KeyCharacterMap from
the file system, get them from the input manager service as
part of the InputDevice object.
Refactored InputManager to be a proper singleton instead of
having a bunch of static methods.
InputManager now maintains a cache of all InputDevice objects
that it has loaded. Currently we never invalidate the cache
which can cause InputDevice to return stale motion ranges if
the device is reconfigured. This will be fixed in a future change.
Added a fake InputDevice with ID -1 to represent the virtual keyboard.

Previously, if an app threw an uncaught exception in an input,
vsync or native activity callback, it would log the exception then
continue limping merrily along. In the case of input, it
could result in an ANR occurring because we had not drained
all of the pending input events and marked them as finished
(we only marked the most recent one finished).

The purpose of the input device descriptor is to make it possible
to associate persistent settings for each input device, such as the
keyboard layout.

Extracted the input system from the window manager service into
a new input manager service. This will make it easier to
offer new input-related features to applications.
Cleaned up the input manager service JNI layer somewhat to get rid
of all of the unnecessary checks for whether the input manager
had been initialized. Simplified the callback layer as well.

SerialManager: provides access to serial ports
SerialPort: for reading and writing data to and from serial ports
IO with both array based and direct ByteBuffers is supported.
Accessing serial ports requires android.permission.SERIAL_PORT permission
Each platform must configure list of supported serial ports in the
config_serialPorts resource overlay
(this is needed to prevent apps from accidentally accessing the bluetooth
or other system UARTs).
In addition, the platform uevent.rc file must set the owner to the
/dev/tty* files to "system" so the framework can access the port.
