- Adds a boolean to BufferQueue that controls whether or not auto
refresh is enabled in SurfaceFlinger when in single buffer mode.
- Adds plumbing up to ANativeWindow.
- When enabled, it will cache the shared buffer slot in Surface in
order to prevent the Binder transaction with SurfaceFlinger.

5ecfb68ffd63d352df0392dca6e95ef67a66c679 05-Jan-2016 Dan Stoza <stoza@google.com> libgui: Fix attaching buffers without allocation

This changes the way that BufferQueue selects slots in
waitForFreeSlotThenRelock. This method is called from both
dequeueBuffer and attachBuffer, but those two methods actually have
different preferences:

dequeueBuffer wants a slot with a buffer if possible (to avoid
unnecessary allocations), but will settle for a slot without a buffer
if no free buffers are available.

attachBuffer wants a slot without a buffer if possible (to avoid
clobbering an existing buffer), but will settle with clobbering a free
buffer if no empty slots are available.

These preferences are now respected, which has the side-effect of
fixing a bug where it was not possible to attach a buffer if allocation
is disabled (since the previous implementation assumed finding a slot
without a buffer meant that the caller intended to allocate a buffer,
which would accordingly be blocked since allocation is disabled).

Adds the ability to specify the timeout when dequeueBuffer or
attachBuffer block due to the lack of a free buffer/slot. By default,
these will block indefinitely (which is signified by a timeout of -1).

When a timeout (other than -1) is specified, non-blocking mode is
disabled and the given timeout will be used instead.

- Adds a single buffer mode to BufferQueue. In this mode designate the
first dequeued buffer as the shared buffer. All calls to dequeue()
and acquire() will then return the shared buffer, allowing the
producer and consumer to share it.
- Modify the buffer slot state tracking. Add a new SHARED state for
the shared buffer in single buffer mode. Also track how many times
a buffer has been dequeued/queued/acquired as it's possible for a
shared buffer to be both dequeued and acquired at the same time, or
dequeued/acquired multiple times. This tracking is needed to know
when to drop the buffer out of the SHARED state after single buffer
mode has been disabled.
- Add plumbing for enabling/disabling single buffer mode from Surface.

- Get rid of the async flag in dequeueBuffer, allocateBuffers,
waitForFreeSlotThenRelock, and QueueBufferInput.
- Instead use the persistent flags mDequeueBufferCannotBlock and
mAsyncMode to determine whether to use the async behavior.

- Remove setBufferCount from BufferQueueProducer and
IGraphicsBufferQueueProducer.
- Get rid of the unit tests for it.
- In Surface, convert setBufferCount calls into calls to
setMaxDequeuedBufferCount.
- Change mOverrideMaxBufferCount to a boolean since it can now be
derived from mMaxAcquiredBufferCount, mMaxDequeuedBufferCount, and
mAsyncMode.

This change allows producers to set a generation number on a
BufferQueue. This number will be embedded in any new GraphicBuffers
created in that BufferQueue, and attempts to attach buffers which have
a different generation number will fail.

It also plumbs the setGenerationNumber method through Surface, with the
additional effect that any buffers attached to the Surface after
setting a new generation number will automatically be updated with the
new number (as opposed to failing, as would happen on through IGBP).

Adds a new method IGBP::allowAllocation, which controls whether
dequeueBuffer is permitted to allocate a new buffer. If allocation is
disallowed, dequeueBuffer will block or return an error as it
normally would (as controlled by *ControlledByApp).

If there are free buffers, but they are not of the correct dimensions,
format, or usage, they may be freed if a more suitable buffer is not
found first.

Passes the BufferItem for the queued buffer to the onFrameAvailable
callback so the consumer can track the BufferQueue's contents. Also
adds an onFrameReplaced callback, which is necessary if the consumer
wants to do anything more than simple queue length tracking.

Throttling was previously controlled by a combination of the
driver and the number of buffers in the queue. This patch makes
a more consistent trade-off, which allows two GPU frames pending
but not three. More buffering could improve throughput in the
case of varying frame times, but this also increases latency.

This adds an allocateBuffers method to BufferQueue, which instructs
it to allocate up to the maximum number of buffers allowed by the
current configuration. The goal is that this method can be called
ahead of render time, which will prevent dequeueBuffers from blocking
in allocation and inducing jank.

This interface is also plumbed up to the native Surface (and, in
another change, up to the Java Surface and ThreadedRenderer).

Adds a new method, IGBP::detachNextBuffer, that effectively does
dequeue + request + detach in a single call, but does not need to
know anything about the dequeued buffer, and will not block on
dequeue. This is mostly for the upcoming StreamSplitter to use in
its onBufferReleased callback.

f0eaf25e9247edf4d124bedaeb863f7abdf35a3e 21-Mar-2014 Dan Stoza <stoza@google.com> BufferQueue: Add producer buffer-released callback

Add a callback to the producer side, onBufferReleased, which will be
called every time the consumer releases a buffer back to the
BufferQueue. This will enable a buffer stream splitter to work
autonomously without having to block on dequeueBuffer.

The binder object used for the callback replaces the generic IBinder
token that was passed into IGraphicBufferProducer::connect to detect
the death of the producer. If a producer does not wish to listen for
buffer release events, it can pass in an instance of the
DummyProducerListener class defined in IProducerListener.h, if it even
cares about death events (BufferQueue doesn't enforce the token being
non-NULL, though perhaps we should).

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.
