After a HWC set, each SurfaceFlinger Layer retrieves the release fence
HWC returned and gives it to the layer's SurfaceTexture. The
SurfaceTexture accumulates the fences into a merged fence until the
next updateTexImage, then passes the merged fence to the BufferQueue
in releaseBuffer.
In a follow-on change, BufferQueue will return the fence along with
the buffer slot in dequeueBuffer. For now, dequeueBuffer waits for the
fence to signal before returning.
The releaseFence default value for BufferQueue::releaseBuffer() is
temporary to avoid transient build breaks with a multi-project
checkin. It'll disappear in the next change.

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.

This change adds support for specifying a crop rectangle to a

SurfaceTexture will modify the crop rect so it matches
the desired output aspect ratio when the scaling
mode is NATIVE_WINDOW_SCALING_MODE_CROP. Added a test

BufferQueue's disconnect could race with updateTexImage
where invalid buffers could be released. Additionally
fixed similar bug with setBufferCount. Tests were added
to stress the disconnect mechanism.

This change adds the detachFromContext and attachToContext methods to
SurfaceTexture. These methods allow the SurfaceTexture to switch from
one consumer GLES context to another. This change also includes a few
cleanups to the error return codes in updateTexImage.

This change adds a check to SurfaceTexture::updateTexImage to verify

previous updateTexImage calls.

This change adds a new callback for BufferQueue consumers to be notified
when the BufferQueue frees some or all of its buffers. This is needed
to retain SurfaceTexture behavior where all buffers would be freed when
the producer disconnects. This change also modifies the
SurfaceTextureGLToGLTest.EglDestroySurfaceUnrefsBuffers test to catch
when the buffers are not freed.
The implementation is a little complicated because it needs to avoid
circular sp<> references across what will be a binder interface (so wp<>
can't be used directly). It also needs to avoid the possibility of
locking the BufferQueue and consumer (e.g. SurfaceTexture) mutexes in
the wrong order.
This change also includes a few additional fixes and test cleanups.

Surface Texture dequeue logic is modified to return the oldest of the
free buffers to Client on dequeue call.
Currently dequeue method is returning the first buffer index which is free.
The parsing is done in ascending order of the buffer slot indices.
This leads to returning the buffer which has been just queued to composer,
and hence display, and this defeats the purpose of having minimum dequeue count
as 2 in asynchrnouse mode.
This is fixed by checking all the free slots and returning the oldest buffer.

we were not reseting mCurrentTexture in some situations
which in turn caused dequeueBuffers() return a
"FREE" buffer that was also current.
Very often it was harmless, but it created a race with
updateTexImage() which could cause the following
queueBuffers() to fail.

we now make sure to drain the buffer queue on disconnect.
this happens only when in synchrnous mode. in async mode
we clear all buffers except the head of the queue.
for extra safety we also catch the null pointer
in updateTexImage (which should never happen) and return
an error.

This change alters the conditions under which the onFrameAvailable
callback gets called by the C++ SurfaceTexture class. The new behavior
is to call the callback whenever a frame gets queued that will be
visible to the buffer consumer. This means that buffers queued in
synchronous mode always trigger the callback, as those buffers will
remain pending until they are consumed. Buffers queued in asynchronous
mode will only trigger the callback if there was not previously an
unconsumed buffer pending.
The new behavior means that a consumer should perform a draw operation
exactly once for every onFrameAvailable call that it recieves. This
change also modifies SurfaceFlinger and the SurfaceTexture JNI to
support of the new behavior.

This change moves the computation of the transform matrix out of
getTransformMatrix and instead performs the computation when
updateTexImage gets called. This is needed in order for
getTransformMatrix to succeed even if the buffers have been freed (e.g.
by changing the buffer count) because the computation depends upon the
properties of the current GraphicBuffer.

This change the binder protocol between SurfaceTextureClient
and SurfaceTexture. dequeueBuffer() now takes the requested
parameters for the buffer. SurfaceTexture decides if the
buffer needs to be reallocated and does the allocation
if needed. In that case it returns BUFFER_NEEDS_REALLOCATION
to tell SurfaceTextureClient that it needs to call
requestBuffer (which all parameters have been removed) to
acquire a pointer to the buffer.
dequeueBuffer and requestBuffer could be folded into a single
IPC call, but we chose to optimize the case where buffers are
not created and avoid some complexity in the marshalling code.
