Any OpenGL memory reported by /proc/pid/smaps will not be included
in the GPU GL memory count and will be considered Unknown. This is
an artifact of how some memory reporting is done in libmemtrack
and some is done in this module.

Also increase the size of the buffer we do need, simplify the code, and
fix some of the error checking.

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.

No longer compile libandroidfw as a static library on the device
since it already exists as a shared library. Keeping the static
library would force us to provide a static library version of
libinput for the device as well which doesn't make sense.

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.
