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.

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.

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.

We now detect at runtime which sync features to use, which
allows us to remove a lot of the compile-time configuration
options. There is still one option though, to disable
KHR_fence_sync on some devices (which are more efficient
without it).
- added a backdoor to get the vendor's EGL strings
the new logic is:
- use always ANDROID_native_fence_sync if available
- fallback to KHR_fence_sync if available and not disabled
by the compile-time option
- use KHR_wait_sync if available and either of the above is
enabled

This change eliminates the uses of a NULL sp<Fence> indicating that no waiting
is required. Instead we use a non-NULL but invalid Fence object for which the
wait methods will return immediately.

The C++ class names don't match what the classes do, so rename
ISurfaceTexture to IGraphicBufferProducer, and SurfaceTexture to
GLConsumer.

This change makes ConsumerBase::onBuffersReleased hold a reference to all its
gralloc buffers until after the mutex is unlocked. This prevents slow
gralloc::free calls from causing lock contention with rendering threads.

This prevents strong reference cycles when the listener implementation also
holds a strong pointer to the ConsumerBase

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.

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.

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.
