When this boardconfig is defined, even when all virtual display
composition is done by GLES, the HWC will be forced to copy from the
GLES framebuffer to the output buffer. On some hardware this allows
HWC to do format conversions that would otherwise have to be done by
the consumer, with worse power and/or performance.

When GLES isn't writing to the output buffer directly, request an
implementation-defined format with minimal usage flags, leaving the
format choice up to gralloc. On some hardware this allows HWC to do
format conversions during composition that would otherwise need to be
done (with worse power and/or performance) by the consumer.

This change allows SurfaceFlinger to run at a different vsync phase offset from
that used by external listeners.

This change adds a new thread for calling HWComposer's eventControl
asynchronously. The DispSync-based vsync approach ends up enabling and
disabling HWComposer's vsync callbacks at arbitrary times, and some HWComposer
implementations do not have these calls optimized.

This change removes the wakeup latency compensation from the software-generated
vsync events. Choreographer can't handle timestamps in the future, so don't
aim for early wake-ups with the expectation that the actual wake-up will be
late.

The screen capture code wasn't waiting for the render to finish,

Bug 11131777
Change-Id: Ic64087322ce3bb15bb5f4fb1eb07579880fe6197
This change adds the DispSync class, which models the hardware vsync event
times to allow vsync event callbacks to be done at an arbitrary phase offset
from the hardware vsync. This can be used to reduce the minimum latency from
Choreographer wake-up to on-screen image presentation.

In GLES-only mode, we don't have the outbuf acquire fence until after
GLES composition is done for the frame. We were setting the fence in
HWC's state immediately after dequeueing the buffer from the consumer,
before GLES had started. This fence got passed through HWC and on to
the consumer, so the consumer was reading the buffer before GLES was
done writing to it.
Now we update HWC's state just before set(), when we know we have the
right fence.

When there are no window layers for a display, SurfaceFlinger clears
the undefined region using GLES. Some of the places that check for
GLES composition weren't considering this special case, in particular:
- We were skipping the eglSwapBuffers() on these frames.
- We were putting VirtualDisplaySurface in HWC-only composition mode.
This change centralizes the logic for this special case.

(a) There is no invalid EGLConfig value, in particular zero is valid.
Checking return values of eglGetConfigs and eglChooseConfig is the
only way to determine success.
(b) The "simple" EGLConfig query used as the emulator fallback should
not include EGL_RECORDABLE; the emulator doesn't have it.

At this time this feature can only be enabled for
debugging:

We simply fix this by setting the scalling mode to

If a layer is not cropped but its bounds are outside of the
viewport (i.e.: clipped), the crop rectangle passed to
hw composer would be invalid because it started invalid
in the first place (to indicate "no crop").

We weren't dequeing and setting the output buffer until just before
set(). This didn't allow HWC to make decisions in prepare() based on
the output buffer format, dimensions, etc.
Now we dequeue the output buffer at the beginning of the composition
loop and provide it to HWC in prepare. In GLES-only rendering, we may
have to cancel the buffer and acquire a new one if GLES requests a
buffer with properties different than the one we already dequeued.

the main reason for doing this is so that we can have
access to informations about a texture (like its dimension)
close to where we generate and use shaders in ES 2.0.
Previously, there wasn't any way to get to a texture's size
from a RenderEngine implementation.

This change adds an entire field to note whether the timestamp was
auto-generated by Surface or supplied by the application.
The value is used when deciding whether or not to drop frames based
on buffer presentation timestamps. If a desired presentation time
was set explicitly, BufferQueue will use that value to decide if a
frame should be dropped. If the timestamp was generated by Surface
at the time the buffer was queued, the timestamp is ignored.

A recent change to screencapture to have the call to
IGraphicBufferProducer happen on the incoming binder
thread didn't set the result so the result was always
returned as NO_ERROR.
This made screencap fail on some devices (e.g. Wolfie)
which relies on some kind of fallback mechanism to
generate the screencap but the fallback mechanism
doesn't get triggered because the error isn't returned.
