e64a79cd85 Fix PTS handling for buffer replacement
This changes the way that SurfaceFlinger's shadow buffer management
works such that instead of tracking the size of the shadow queue in the
BufferQueue, SF tracks the last frame number it has seen, and passes
that into the acquireBuffer call. BufferQueueConsumer then ensures that
it never returns a buffer newer than that frame number, even if that
means that it must return PRESENT_LATER for an otherwise valid buffer.

This completes the plumbing from ConsumerListener::onFrameReplaced into
SurfaceFlinger (and other consumers that may care).

634f5ee6a7 libgui: Plumb detachBuffer through ConsumerBase
Exposes IGraphicBufferConsumer::detachBuffer as a ConsumerBase
method. attachBuffer is not currently exposed, because all current
clients will be recycling buffers through the allocator.

cf3834db10 DO NOT MERGE libgui: Prepare for IGBC::BufferItem removal
Currently, there are two instances of BufferItem: one inside of
IGraphicBufferConsumer, and a standalone one inside of libgui. They
only differ in the name of one of the fields, and we want to remove
the IGBC version. This changes things so that client code may be
incrementally switched over to the libgui version.

8dc55396fc Add a BufferItem parameter to onFrameAvailable
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.

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.

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

595264f1af 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.

1585c4d9fb Pay attention to buffer timestamps
When acquiring a buffer, SurfaceFlinger now computes the expected
presentation time and passes it to the BufferQueue acquireBuffer()
method.  If it's not yet time to display the buffer, acquireBuffer()
returns PRESENT_LATER instead of a buffer.

The current implementation of the expected-present-time computation
uses approximations and guesswork.

c5d7b7d323 BufferQueue: track buffer-queue by instance vs. by reference
Instead of representing the buffer-queue as a vector of buffer
indices, represent them as a vector of BufferItems (copies).
This allows modifying the buffer slots independent of the queued
buffers.

As part of this change, BufferSlot properties that are only
been relevant in the buffer-queue have been removed.

Also, invalid scalingMode in queueBuffer now returns an error.

ConsumerBase has also changed to allow reuse of the same
buffer slots by different buffers.

ad669b04f4 libgui: fix an EGLImage leak
This moves the call to ConsumerBase::abandon from the ConsumerBase dtor to
ConsumerBase::onLastStrongRef.  The abandon call relies on virtual methods to
perform the clean-up, so calling it from the ConsumerBase dtor after the
derived classes dtors ran was skipping some of the clean-up.  The
onLastStrongRef method should get called just before the most derived class's
dtor gets called.

7adb0f8a9f Minor cleanups/fixes before virtual display refactoring
None of these should change behavior, except for removing some
incorrect log messages when using a virtual display.

- HWComposer::getAndResetReleaseFenceFd() checks the HWC version, so
  no need to do that in the DisplayDevice::onSwapBuffersCompleted().
  However, it should check that mFramebufferSurface is not NULL like
  it is for virtual displays.
- Comment that FramebufferSurface::dump() overrides the non-virtual
  ConsumerBase::dump(), and fix it so the right thing happens
  regardless of the static type of the pointer/reference the callee
  has. FramebufferSurface::dump() could be removed right now, but I'd
  need to bring it back in a later change.
- Use the right enum for validating display type ids.
- Don't try to send hotplug events for virtual displays.
- Mark virtual displays as connected so HWComposer::prepare() doesn't
  think something is wrong when it gets a non-NULL layer list.
- Remove unused FramebufferSurface methods.

9504eb915c Fix race condition in ConsumerBase::addReleaseFence()
This needs the ConsumerBase mutex locked, but wasn't locking it. Two
of the four places that called it already held the lock so were fine.
Now addReleaseFence() takes the lock itself, and I added
addReleaseFenceLocked() for the two already-locked callers, since in
one of them dropping the lock would be inconvenient.

b272541546 libgui: move fence handling into ConsumerBase
This change moves some common fence handling code into the base class for
BufferQueue consumer classes.  It also makes the ConsumerBase class initialize
a buffer slot's fence with the acquire fence every time a buffer is acquired.

9fea3421ff SurfaceTexture: inherit from ConsumerBase (try 2)
This change makes SurfaceTexture inherit from ConsumerBase.  It removes all of
the functionality from SurfaceTexture that is now provided by the base class.
This includes fixes for two bugs that were found after checking this change in
the first time and then reverting it.
