e41b318bc4 Add a BufferQueue CPU consumer.
Aimed for use cases where gralloc buffers need to be consumed by CPU
users, such as camera image data streams.

The CpuConsumer is a synchronous queue, which exposes raw pointers to
the underlying graphics buffers to applications. Multiple buffers may
be acquired at once, up to the limit set at time of construction.

d72f233ffa libgui: Add support for post-xform crops.
This change adds support for specifying a crop rectangle to a
SurfaceTextureClient that is in post-transformed coordinate space.

efc7ab6dce libgui: Add plumbing for active rectangle
This change adds the plumbing to SurfaceTextureClient, BufferQueue, and
SurfaceTexture to get the active rectangle passed to the ANativeWindow to
the buffer consumer.

24202f5676 update the binder protocol for connect to match that of queueBuffer
indeed, connect and queueBuffer return the same data, so it's
easier to have them use the same protocol.

fbcda930dd BufferQueue returns proper code on acquire
Also removed unnecessary debug messages from
SurfaceTextureClient.

abe61bfda4 BufferQueue no longer hardcodes buffer counts
BufferQueue is now more flexible as it can be used
by SurfaceMediaSource in addition to SurfaceTexture.

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.

851ef8f1bf reduce IPC with BufferQueue
collapse setCrop, setTransform and setScalingMode to queueBuffer()
this ends up simplifying things quite a bit and reducing the numnber
of IPC needed per frame.

f71c4ae136 Added a DummyConsumer for use with BufferQueue.
The DummyConsumer is a consumer that can connect to BufferQueue
that does nothing.  It is required as BufferQueue checks
if a consumer is connected.  Also fixes a bug where SurfaceTexture
was reusing old texture slots.

fa5b40ebb8 libgui: add BQ consumer buffer free notifications
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.

eae59d2ea7 Removed dependecies between BufferQueue and SurfaceTexture
Refactored SurfaceTexture and BufferQueue such that share
no protected members.  Created an consumer facing interface
for BufferQueue in preparation of connecting SurfaceTexture
and BufferQueue through a binder.
