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".

3c25621ad7 Re-enable frame dropping for non-auto timestamps
This change adds an entire field to note whether the timestamp was
auto-generated by Surface or supplied by the application.

The value is used when deciding whether or not to drop frames based
on buffer presentation timestamps.  If a desired presentation time
was set explicitly, BufferQueue will use that value to decide if a
frame should be dropped.  If the timestamp was generated by Surface
at the time the buffer was queued, the timestamp is ignored.

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

a4e19521ac Binderize the consumer side of BufferQueue
While currently untested, this should allow to move the
BuffereQueue in the consumer process and have everything
work as usual.
