If module composition type is MDP or C2D and we have a skipped layer
(usually layers without backing buffers, layers with "invalid"
orientations or debug layers), mark every HWC layer below this layer
for GPU composition.
This logic is needed because ICS SF composes a bunch of z-ordered
HWC_FRAMEBUFFER (GPU) layers first and then the remaining bunch of
z-ordered HWC_OVERLAY layers last which breaks the overall z-ordered
layer rendering requirement. This logic also holds valid for 2-layer
bypass in ICS.

Validate the previous overlay and bypass handles before unlocking
the buffers. The reason for doing this, is that in certain use cases,
after the previous handles are stored, the buffer gets destroyed and the
handle is now invalid. The HWC however doesn't know that the handle is
invalid and tries to unlock the handle, resulting in a failure.

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.

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.

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).

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.

Whenever there is a change in the buffer geometry, set a flag in the

the overlay information and not unnecessarily open/close channels.
