When reading from the end of a pipe or socket, there is no way to
tell if the other end has finished successfully, encountered an error,
or outright crashed. To solve this, we create a second socketpair()
as a communication channel between the two ends of a pipe or
socket pair, sending a status code with details about why the
ParcelFileDescriptor was closed.
The writer end of a pipe or socket can closeWithError() to send a
message to the reader end. When the reader encounters EOF, they
call checkError() to detect if any error occured. This also detects
the case where the remote process died without sending a success
message.
This design is also extended to support regular files on disk, using
the communication channel above to detect various remote close events
or crashes, and delivering that event to a supplied OnCloseListener.
Replaces JNI with best-practice Libcore.os calls, and deprecates
some flags to match Context.

To allow low-memory devices to reduce (or eliminate entirely)
the RAM used by the JIT, dalvikvm has a new command-line
option to set the max size of the JIT's translation cache.
In this CL, we pass that new option based on a system property.

When the Android runtime starts, the system preloads a series of assets
in the Zygote process. These assets are shared across all processes.
Unfortunately, each one of these assets is later uploaded in its own
OpenGL texture, once per process. This wastes memory and generates
unnecessary OpenGL state changes.
This CL introduces an asset server that provides an atlas to all processes.
Note: bitmaps used by skia shaders are *not* sampled from the atlas.
It's an uncommon use case and would require extra texture transforms
in the GL shaders.
WHAT IS THE ASSETS ATLAS
The "assets atlas" is a single, shareable graphic buffer that contains
all the system's preloaded bitmap drawables (this includes 9-patches.)
The atlas is made of two distinct objects: the graphic buffer that
contains the actual pixels and the map which indicates where each
preloaded bitmap can be found in the atlas (essentially a pair of
x and y coordinates.)
HOW IS THE ASSETS ATLAS GENERATED
Because we need to support a wide variety of devices and because it
is easy to change the list of preloaded drawables, the atlas is
generated at runtime, during the startup phase of the system process.
There are several steps that lead to the atlas generation:
1. If the device is booting for the first time, or if the device was
updated, we need to find the best atlas configuration. To do so,
the atlas service tries a number of width, height and algorithm
variations that allows us to pack as many assets as possible while
using as little memory as possible. Once a best configuration is found,
it gets written to disk in /data/system/framework_atlas
2. Given a best configuration (algorithm variant, dimensions and
number of bitmaps that can be packed in the atlas), the atlas service
packs all the preloaded bitmaps into a single graphic buffer object.
3. The packing is done using Skia in a temporary native bitmap. The
Skia bitmap is then copied into the graphic buffer using OpenGL ES
to benefit from texture swizzling.
HOW PROCESSES USE THE ATLAS
Whenever a process' hardware renderer initializes its EGL context,
it queries the atlas service for the graphic buffer and the map.
It is important to remember that both the context and the map will
be valid for the lifetime of the hardware renderer (if the system
process goes down, all apps get killed as well.)
Every time the hardware renderer needs to render a bitmap, it first
checks whether the bitmap can be found in the assets atlas. When
the bitmap is part of the atlas, texture coordinates are remapped
appropriately before rendering.

The input method manager service now supplies an input channel for
communication while creating an IME session on behalf of the
application.
This change significanly reduces the overhead of IME event dispatch
by using a standard input channel to send input events rather than
using binder. This results in fewer thread context switches
and fewer object allocations.
What's more, the IME may perform additional batching of the motion
events that it receives which may help it catch up if it is
getting behind while processing them.

SurfaceControl is the window manager side; it can
control the attributes of a surface but cannot push buffers
to it. Surface on the other hand is the application (producer)
side and is used to push buffers to the surface.

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.
Change-Id: I2a658f1bfd0437e1c6f9d22df8d4ffcce7284ca2
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.

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.

There is no graceful way to kill Android application processes.
They typically have many threads running doing various things
When System.exit() is called, those threads just keep going
while the cleanup actions run until the process finally.
Performing shutdown actions can easily cause more harm than good.
For example, closing the Binder driver's file descriptor may
cause other threads waiting on Binder to wake up and then crash
in nasty ways after receiving EBADF.
So when an Android application exits, skip the cleanup and just
call _exit() to end it all.

Basic functionality of handling View properties (transforms,
left/right/top/bottom, and alpha) at the native DisplayList level.
This logic is disabled for now (via compile-time flags in View.java and
DisplayListRenderer.h) as we continue work on it (there is no advantage
to the new approach until we optimize invalidation and rendering paths
to use the new code path).

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.
