042ecee2ab CpuConsumer: Properly track acquired buffers
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.

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.

e232fdca2a 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'.

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.
