Android YUV formats are aligned to 16pixels, while C2D requires 32pixel
aligned. Use a temp buffer to do the conversion.

Since composition bypass uses MDP overlays, which
need physically contiguous memory, we cannot use
bypass in cases where the buffers are using ashmem
or other virtual memory. Hence, avoid bypass in
such cases.

Add support to set the framebuffer width and height in the copybit
context. This parameter will be set for composition using c2d where
the c2d target is calculated based on the framebuffer width and height.

Synchronize turning off of composition bypass with display,
so that close happens only after FB content is displayed.
This fixes blinks observed when bypass needs to be turned off,
for reasons other than video content.

If the input parameters in the prepare and set functions are invalid, unlock
any previously locked buffers.

Add HAL_PIXEL_FORMAT_NV12_ENCODEABLE which is the encoder specific
format.
Remove unused OEM formats from the gralloc.

Use genlock to lock the bypass buffers before they are queued to the
overlay. After all the bypass buffers are queued, use genlock to
unlock the previously locked bypass buffers.

When queuing buffers using the overlay:
- Set the NO_WAIT flag for the HDMI channel.
- Set the WAIT flag for the primary channel.
- Queue the buffer on the HDMI first.
- Queue the buffer on the primary.
- Wait for the HDMI Vsync.

For copybit composition, aquire a read lock on the buffer, before
the blit operation and release the lock after the blit operation.
For overlay, aquire a read lock on buffer N that is sent to the
overlay. After the play call for buffer N returns, unlock the lock
held by buffer (N-1).

Map the gralloc buffer during the register_buffer phase. This allows
the clients to obtain the virtual address without the need to call an
additional mmap.

Add support in the gralloc to:
- Create a lock during buffer allocation.
- Release a lock when the buffer is freed or unregistered.
- Attach a lock when the buffer is registered.

Add libgenlock which is a cross-process buffer locking API. libgenlock
provides the ability to create, attach, release locks. It also provides
a mechanism to lock and unlock buffers for read/write purposes.

1. Enable composition bypass for 1 or 2 non-overlapping layers.
2. Open bypass only if video playback status is CLOSED.
3. Close bypass immediately if Video or Camera needs VG pipe.

This change enables c2d composition in HWC by removing the temporary
flag added in the following commit:

Add the copybit header file in the libcopybit directory. Modify the
copybit source files to read from the correct header file.

-- Enable HWC
-- handle overlay as lib rather than HAL
-- move copybit changes under COPYBIT_ENABLE flag (temporary)
