- Return NOT_ENOUGH_DATA instead of INVALID_OPERATION when too many
buffers have already been locked.
- INVALID_OPERATION is nominally used when something irrecoverable happens,
but in this case the client just needs to call unlockBuffer to go back into a
good state.

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

595264f1af12e25dce57d7c5b1d52ed86ac0d0c9 17-Jul-2013 Mathias Agopian <mathias@google.com> BufferQueue improvements and APIs changes

this is the first step of a series of improvements to
BufferQueue. A few things happen in this change:

- setSynchronousMode() goes away as well as the SynchronousModeAllowed flag
- BufferQueue now defaults to (what used to be) synchronous mode
- a new "controlled by app" flag is passed when creating consumers and producers
those flags are used to put the BufferQueue in a mode where it
will never block if both flags are set. This is achieved by:
- returning an error from dequeueBuffer() if it would block
- making sure a buffer is always available by replacing
the previous buffer with the new one in queueBuffer()
(note: this is similar to what asynchrnous mode used to be)

Note: in this change EGL's swap-interval 0 is broken; this will be
fixed in another change.

Add setDefaultBufferSize() and setDefaultBufferFormat(). ImageReader JNI need
them.

CpuConsumer cannot simply assume a slot's buffer is the same buffer
between acquire and release, and therefore it could be possible for
the same slot to get used for a second acquired buffer, if there's a
producer disconnect in between. This would cause a problem when the
first buffer is released by the consumer.

Instead, use an independent list of acquired buffers to properly track
their state.

ISurfaceTexture to IGraphicBufferProducer, and SurfaceTexture to
GLConsumer.

e232fdca2a62dc5e81b550f5be8710e36174e7a6 21-Aug-2012 Eino-Ville Talvala <etalvala@google.com> Add BufferItemConsumer, a simple BufferQueue consumer.

BufferItemConsumer allows for acquiring BufferQueue's BufferItems,
which contain all the data and metadata the BufferQueue has for a
given graphics buffer.

This consumer is useful when direct access to the native buffer_handles
is needed by the client.

Also includes a minor cleanup of CpuConsumer's use of 'virtual'.

e41b318bc4708e1dee9364e73215ff0d51fb76a1 17-Apr-2012 Eino-Ville Talvala <etalvala@google.com> 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.
