Increases NUM_BUFFER_SLOTS from 32 to 64 and changes the mask
returned by IGBC::getReleasedBuffers from 32 to 64 bits.

99b18b447dec188bcec37b415603b9dd400fc7e1 28-Mar-2014 Dan Stoza <stoza@google.com> BufferQueue: Add StreamSplitter

Adds a StreamSplitter class, that takes one IGraphicBufferConsumer
interface and multiple IGraphicBufferProducer interfaces and
implements a one-to-many broadcast of GraphicBuffers (while managing
fences correctly).

Adds a test that puts the BufferQueue into its own process and
connects to it over remote binder interfaces. This exposed the fact
that while IGBC was technically binderized, it didn't actually work
when flattened, so this change also fixes that.

399184a4cd728ea1421fb0bc1722274a29e38f4a 04-Mar-2014 Jesse Hall <jessehall@google.com> 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

Adds detachBuffer and attachBuffer calls to both the producer and
consumer sides of BufferQueue. Buffers may be detached while dequeued
by the producer or acquired by the consumer, and when attached, enter
the dequeued and acquired states, respectively.

we add a flag to ANativeWindow::setBufferTransform that means
"apply the inverse rotation of the display this buffer is displayed
onto to".

3c25621ad7d13f64d3ab95a27fa970fbc9998f73 16-Aug-2013 Andy McFadden <fadden@android.com> 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.

db89edc94bd2a78226b407f9f7261e202e7fa325 02-Aug-2013 Mathias Agopian <mathias@google.com> 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

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