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.

Now that we are having separate buffer-instances for the buffer-
queue, we can free all buffers; we don't have to keep the head
alive.

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 change fixes how the MultiTextureConsumerTest.EGLImageTargetWorks checks
for pixels. It removes the call to eglSwapBuffers so that the test does not
rely on EGL swap-preserve behavior, and it makes the test use checkPixel()
rather than doing glReadPixels itself.

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

We're not using IMemoryHeap as a transport anymore,
instead we're providing a CpuConsumer and use the
IGraphicBufferProducer version of the screenshot API.
However, some GPU drivers don't support properly
a GPU to CPU path, to work around this, we use a
temporary BufferQueue on the server side for the
GL rendering, and we use glReadPixels into the
CpuConsumer (we're now using a CPU to CPU path
which is always supported).
Currently this "wrapping" is always performed,
but it can be bypassed on devices that support
the GPU to CPU path.
This also addresses a DoS attack vector on
SurfaceFlinger, where an application could
consume all of SF's filedescriptors by creating
a lot of screenshots in a row.

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.

This change fixes a number of small glitches that can occur when
multiple components in the same process are updating surfaces.
One would expect that updates to disjoint sets of surfaces would
not collide but this is not the case. The first component to
close the global transaction causes all pending updates to
be applied, including those that another component might not
have finished setting up if it also had an open transaction
at the same time.

This needs the ConsumerBase mutex locked, but wasn't locking it. Two

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 fixes an issue causing the mEglContext member of a SurfaceTexture
to get incorrectly zeroed out. This would happen when a call to
ConsumerBase::releaseBufferLocked resulted in the current buffer being freed.
Freeing the current buffer would set SurfaceTexture::mCurrentTexture to -1,
which would then be used by SurfaceTexture::releaseBufferLocked to reset the
current slot's EGLSyncKHR to EGL_NO_SYNC_KHR (= 0). This would overwrite the
mEglContext field, resulting in context mismatch errors in
SurfaceTexture::doGLFenceWaitLocked.
The fix is to simply use the buffer slot that's passed in to
SurfaceTexture::releaseBufferLocked rather than mCurrentTexture.

its own wait on the fence.
