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.

This lets audioflinger assign blame for wakelocks to a single uid.
Currently this is only used for recording wakelocks.

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.

This change makes GLConsumer use the EGL_ANDROID_image_crop extension when
available on a device. The crop rectangle is passed to the EGL driver when
creating EGLImages, allowing the crop to be performed by the driver rather than
using the texture transform matrix.

This fixes two bugs introduced by
Change-Id: Ia8cc084c02a0e3de910def024da8a08d02bbd89d
(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.
