399184a4cd Add sideband streams to BufferQueue and related classes
Sideband streams are essentially a device-specific buffer queue that
bypasses the BufferQueue system. They can be used for situations with
hard real-time requirements like high-quality TV and video playback
with A/V sync. A handle to the stream is provided by the source HAL,
and attached to a BufferQueue. The sink HAL can read buffers via the
stream handle rather than acquiring individual buffers from the
BufferQueue.

c1c05de415 fix camera API 2.0 orientation
we add a flag to ANativeWindow::setBufferTransform that means
"apply the inverse rotation of the display this buffer is displayed
onto to".

db89edc94b All consumers now take an IGraphicBufferConsumer instead of a BufferQueue
this means they only have access to the consumer end of
the interface. we had a lot of code that assumed consumers
where holding a BufferQueue (i.e.: both ends), so most of
this change is untangling in fix that

1585c4d9fb Pay attention to buffer timestamps
When acquiring a buffer, SurfaceFlinger now computes the expected
presentation time and passes it to the BufferQueue acquireBuffer()
method.  If it's not yet time to display the buffer, acquireBuffer()
returns PRESENT_LATER instead of a buffer.

The current implementation of the expected-present-time computation
uses approximations and guesswork.

2adaf04fab Rename ISurfaceTexture and SurfaceTexture
The C++ class names don't match what the classes do, so rename
ISurfaceTexture to IGraphicBufferProducer, and SurfaceTexture to
GLConsumer.

97eba8904c Avoid unnecessary texture bind
In SurfaceFlingerConsumer, check to see if native fence sync is
enabled.  If so, defer the texture binding step to Layer::onDraw.

bf974abe92 Refactor SurfaceTexture a bit.
Rearranges updateTexImage() so that the SurfaceFlinger-specific
behavior is in a new SurfaceFlingerConsumer subclass.

SurfaceTexture behavior should not be altered.  Instead of
acquire-bind-release we now do acquire-release-bind, but since
it's all done with the lock held there shouldn't be any
externally-visible change.
