fb1b5a2f33 SurfaceTexture: parameterize the texture target
This change adds a hack to allow Android Browser to use a SurfaceTexture
to stream RGBA images to a GL_TEXTURE_2D texture object.

29b5762efc don't return the current buffer from dequeueBuffer
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.

8e19c2e97e fix a crasher in SurfaceTexture::updateTexImage()
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.

5bfc24515b return correct value from query after connecting a surface
the first time a surface was connected, the values returned
by query NATIVE_WINDOW_DEFAULT_{WIDTH|HEIGHT} and
NATIVE_WINDOW_TRANSFORM_HINT were wrong until a call
to queueBuffer was performed.

3d8063b02e SurfaceTexture: change onFrameAvailable behavior
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.

736aa9573b SurfaceTexture: fix a getTransformMatrix crash.
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.

c04f153353 Fix a bug where setgeometry couldn't be undone
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.

4cb18881b5 Fix a GraphicBuffer leak in SurfaceTexture
This leak was intentional, it was there to deal with the fact that
some gralloc implementations don't track buffer handles with
file-descriptors so buffers needed to stay alive until there were
registered, which is not guaranteed by binder transactions.

In this new implementation, we use a small BBinder holding a
reference to the buffer, which with tuck into the parcel. This forces
the reference to stay alive until the parcel is destroyed, which
is guaranteed (by construction) to happen after the buffer is
registered.

this allows the public facing API to not expose the previous hack.

a5c75c0162 SurfaceTexture can now force the client to request a buffer
SurfaceTexture now has the concept of default size a new method,
setDefaultBufferSize() to set it. When the default size is
changed, dequeueBuffer() will return a value telling the
client that it must ask for a new buffer.

The above only applies if the client has not
overriden the buffer size with setGeometry.

1d01a12e71 Add support for timestamps into SurfaceTexture.
API addition: The timestamps are represented as nanoseconds from some
arbitrary time point. Like the SurfaceTexture transform matrix, the
timestamp retrieved by getTimestamp is for the last frame sent to the
GL texture using updateTexImage().

Camera HAL change: Expect vendors to set these timestamps using
native_window_set_buffers_timestamp().  For now, they are
autogenerated by SurfaceTextureClient if set_buffers_timestamp() is
never called, but such timing is likely not accurate enough to pass a
CTS test.

1b20cde313 Pass the IGraphicBufferAlloc to SurfaceTextureClient.
This change passes a reference to the IGraphicBufferAlloc binder object
to SurfaceTextureClient objects.  When STC objects are created they
query their associated ISurfaceTexture object for the
IGraphicBufferAlloc that the SurfaceTexture uses to allocate buffers.
Having the SurfaceTextureClient hold this reference prevents the
GraphicBufferAlloc in SurfaceFlinger from freeing the allocated buffers
before the SurfaceTextureClient is done with them.

9a78c90cd4 Fix remote GraphicBuffer allocation in SurfaceFlinger.
This change fixes a horrible hack that I did to allow application
processes to create GraphicBuffer objects by making a binder call to
SurfaceFlinger.  This change introduces a new binder interface
specifically for doing this, and does it in such a way that
SurfaceFlinger will maintain a reference to the buffers until the app is
done with them.
