There was an issue in Surface::lock where failure to lock a surface
resulted in two bad things happening:
- success was returned to the caller (it was apparently locked).
- an uninitialised pointer was returned as the buffer.

When the app_process is shutting down the main thread will close the
binder fd while pool threads are executing an ioctl (in
IPCThreadState::stopProcess called by AppRuntime::onStarted in
app_main.c).
The binder driver will then return all pending calls in ioctl
without any error and with a command. One of the threads gets a
BR_SPAWN_LOOPER which will create a new thread (the other thread
gets a BR_NOOP). This new thread then calls
vm->AttachCurrentThread. Usually this results in a log entry with
"AndroidRuntime: NOTE: attach of thread 'Binder Thread #3' failed",
but sometimes it also causes a SIGSEGV. This depends on the timing
between the new thread an the main thread that calls DestroyJavaVM
(in AndroidRuntime::start).
If IPCThreadState.cpp is compiled with "#define LOG_NDEBUG 0" the
pool thread will loop and hit the
ALOG_ASSERT(mProcess->mDriverFD >= 0) in
IPCThreadState::talkWithDriver.
Crashes like this has been seen when running the am command and
other commands that use the app_process.
This fix makes sure that any command that is received when the driver
fd is closed are ignored and IPCThreadState::talkWithDriver instead
returns an error which will cause the pool thread to exit and detach
itself from the vm. A check to avoid calling ioctl to a fd with -1
was also added in IPCThreadState::threadDestructor.
Another solution might be to change the binder driver so that it
returns an error when the fd is closed (or atleast not a
BR_SPAWN_LOOPER command). It might also be possible to call exit(0)
which is done when System.exit(0) is called from java.

The Java implementation of writing the RPC response header
calculates the length of the header including the 4 bytes
specifying the header length but the native implementation
excludes the 4 bytes specifying the length from the header
length.
The native implementation has been aligned to the Java impl.

this prevents SurfaceTexture producer to hang in dequeueBuffer()
when something goes wrong in the consumer.
only the consumer gets an error and the current frame is kept
instead of the new one. the producer is unaware of the problem.

SurfaceTexture would only create an EGLImage for a buffer slot when
BufferQueue returns a GraphicBuffer, i.e. either the slot was acquired
for the first time ever, or the buffer for the slot was reallocated.
But the EGLImage may also need to be re-created for a
previously-acquired buffer if the slot's EGLImage was destroyed during
detachFromContext(); in this case BufferQueue won't return a
GraphicBuffer since SurfaceTexture already has a reference to the
correct buffer.

Previous kernels have allowed opening the CPU frequency file regardless
whether the CPU is up or not. This fixes some log spam on one device
with dynamic hot plug CPU feature, which does not allow opening the CPU
frequency file if CPU is down.
Also, since the file descriptors are global and have long lives, add
the close-on-exec flag.

This change adds a crop rectangle specified in window coordinates to the layer
state. The all window pixels outside this crop rectangle are treated as though
they were fully transparent. This change also adds the plumbing necessary for
WindowManager to set that crop.

This change updates some of the SurfaceTextureClient and BufferQueue logging

the uses of the NO_SCALE_CROP scaling mode enum, which was added by accident in
a previous change.

Every IBinder object can accept a new transaction to tell it that
it might want to reload system properties, and in the process
anyone can register a callback to be executed when this happens.
Use this to reload the trace property.
This is very much ONLY for debugging.

This change reduces the shrinking of the crop rectangle in some cases. It adds
a way to inform the SurfaceTexture that its texture will be used without
bilinear interpolation, and uses knowledge of the pixel format to avoid
shrinking unecessarily.

Remove C++ APIs androidSetThreadSchedulingGroup and
androidGetThreadSchedulingGroup, and the ANDROID_TGROUP_* constants.
Former callers of these should now use the C APIs set_sched_policy and
get_sched_policy, and the SP_* constants.
Note: debug.sys.noschedgroups is not supported by the C APIs,
this needs to be discussed.

This change fixes an issue where we were sometimes setting the SurfaceTexture's
EGLDisplay to EGL_NO_DISPLAY in detachFromContext, and then subsequently
abandoning the texture. Abandoning while in the detached state would result in
the eglDestroyImageKHR calls failing, which resulted in a memory leak.
