Daniel Lam 9abe1ebc95 Fixed disconnect bug in SurfaceTexture 
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 test fixture is for testing GL -> GL texture streaming from one thread
* to another. It contains functionality to create a producer thread that will
* perform GL rendering to an ANativeWindow that feeds frames to a
* SurfaceTexture. Additionally it supports interlocking the producer and
* consumer threads so that a specific sequence of calls can be
* deterministically created by the test.
*
* The intended usage is as follows:
*
* TEST_F(...) {
* class PT : public ProducerThread {
* virtual void render() {
* ...
* swapBuffers();
* }
* };
*
* runProducerThread(new PT());
*
* // The order of these calls will vary from test to test and may include
* // multiple frames and additional operations (e.g. GL rendering from the
* // texture).
* fc->waitForFrame();
* mST->updateTexImage();
* fc->finishFrame();
