we can now queue/dequeue a buffer in asynchrnous mode by using the
async parameter to these calls. async mode is only specified
with those calls (it is not modal anymore).
as a consequence it can only be specified when the buffer count
is not overidden, as error is returned otherwise.

we tag queued buffers with the "bufferqueue cannot block" flag
and use that bit to discard a buffer in the queue by new ones
comming in. this allows us to remove the buffer queue drain in
disconnect while maintaining the right behaviour if it gets
connected again (since each buffer remembers how it was enqueued).

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.

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.

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 check that the order in which we destroy GLConsumer wrt.
releasing the corresponding EGLSurface via eglMake(Un)Current
doesn't leak a buffer.
On at least 2 devices this test doesn't pass.

We check that calling eglSwapBuffers() on an abandonned BufferQueue
return EGL_BAD_SURFACE -- this is to ensure consistancy between
drivers.

This change eliminates the uses of a NULL sp<Fence> indicating that no waiting

This change adds some infrastructure for testing the BufferQueue class. It
also includes a test that tests the new check in BufferQueue::acquireBuffer
that prevents the consumer from acquiring more than one buffer beyond the max
acquired buffer count that was set.

This change is a clean up of some of the handling of the maximum number of
buffers that are allowed at once. It mostly renames a few member variables and
methods, but it includes a couple small refactorings.

Use only display tokens in the API to refer to new displays.
Don't require the caller to specify the display when creating
a surface (since in general a surface could be shown on
any display).
This is intended to be a minimum change just to update the API.
Note that SurfaceFlinger still uses DisplayID in a few places
internally that might cause some features not to work properly
when there are multiple displays (LayerScreenshot, for example).

SurfaceTexture would only create an EGLImage for a buffer slot when
BufferQueue returns a GraphicBuffer, i.e. either the slot was acquired
for the first time ever, or the buffer for the slot was reallocated.
But the EGLImage may also need to be re-created for a
previously-acquired buffer if the slot's EGLImage was destroyed during
detachFromContext(); in this case BufferQueue won't return a
GraphicBuffer since SurfaceTexture already has a reference to the
correct buffer.

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.

SurfaceTexture to get the active rectangle passed to the ANativeWindow to
the buffer consumer.

This change makes SurfaceTexture include an offset for all sides of the crop
region when cropping. This keeps the image centered, to minimize the visual
changes when switching between the texture transform matrix-based cropping and
something that does proper cropping (e.g. HWComposer).

SurfaceTexture will modify the crop rect so it matches
the desired output aspect ratio when the scaling
mode is NATIVE_WINDOW_SCALING_MODE_CROP. Added a test
for this new scaling mode.

BufferQueue's disconnect could race with updateTexImage
where invalid buffers could be released. Additionally
fixed similar bug with setBufferCount. Tests were added
to stress the disconnect mechanism.

This change adds the detachFromContext and attachToContext methods to
SurfaceTexture. These methods allow the SurfaceTexture to switch from
one consumer GLES context to another. This change also includes a few
cleanups to the error return codes in updateTexImage.

that the current GL context is the same as the one that was used for
previous updateTexImage calls.
Change-Id: If02d2f787bcfdb528046dc9ddf6665f8a90e1bf4
This change adds a new callback for BufferQueue consumers to be notified
when the BufferQueue frees some or all of its buffers. This is needed
to retain SurfaceTexture behavior where all buffers would be freed when
the producer disconnects. This change also modifies the
SurfaceTextureGLToGLTest.EglDestroySurfaceUnrefsBuffers test to catch
when the buffers are not freed.
The implementation is a little complicated because it needs to avoid
circular sp<> references across what will be a binder interface (so wp<>
can't be used directly). It also needs to avoid the possibility of
locking the BufferQueue and consumer (e.g. SurfaceTexture) mutexes in
the wrong order.
This change also includes a few additional fixes and test cleanups.
