Put HDMI code in HWC under compile time flag.
This prevents crashes in use cases like HDMI used as primary.
If not done, non-existing code in gralloc is called in that
use case.

The overlay_buffer_info buffer geometry and size. When calling the
overlay from the gralloc or hardware composer, populate this structure
with the information from the gralloc handle.

Separate overlay setup and overlay play.
On setup failure, mark the layer to use C2D if enabled.
Else mark the layer to use GPU.

If SurfaceFlinger marks a layer with the HWC_DO_NOT_USE_OVERLAY
flag, do not use the overlay to draw the layer

If we have only one overlay layer, and the rest of the layers
are not updating, set the HWC_SKIP_COMPOSITION flag to inform
SurfaceFlinger not to compose anything. Also skip the drawing of
any UI frames and swapping the buffers.

If the layer blending has been disabled, disable copybit alpha so
that copybit does not perform any blend operation.

- Inform the gralloc of the HDMI status.
- If the HDMI is disconnected, close the overlay and also inform the
gralloc that video mirroring has stopped.

Whenever there is a change in the buffer geometry, set a flag in the
gralloc handle stating that the buffer geometry has changed.
In the HWC, whenever we encounter an update in the geometry, if the
channel is already open, we just call the necessary ioctls to update
the overlay information and not unnecessarily open/close channels.

When the layer flags are marked to maintain the original surface
resolution, draw the layer using the overlay.
Store the HDMI status in the overlay object instead of the HWC
context.
Set the correct parameters for the source and destination rectangles
when drawing the layer using copybit.

SurfaceFlinger calls a hwc_set with a NULL context and
list when it is releasing the HWC. Check the validity
of the pointers before using it.

Enable video on HDMI when cable is connected.
Inform gralloc module when video playback starts and stops.

Initial HWC changes
- Add support to recognize video/camera buffers in the prepare phase
- Use overlays to draw single video/camera layers
