Jamie Gennis 5451d15ee2 SurfaceTexture: add some GL->GL tests. 
This change adds some tests to verify streaming images from one GL
thread to another via SurfaceTexture.  Currently the tests do not
validate the correctness of the streamed images, but rather simply
verify that this streaming does not cause a deadlock.  3 of the 4 tests
are currently disabled because they do cause deadlocks on some devices.

/*
* This test is for testing GL -> GL texture streaming via SurfaceTexture. 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

* // texture).
