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)

Android uses different alignments for YV12 buffers.
Hence, introduce a new format (MDP_Y_CR_CB_GH2V2) for
such buffers.

When the source for rotator is the
framebuffer, the FB flag needs to be set
to identify the type of memory to be used.

Allow 1 or 2 non overlapping layers to use composition bypass.
This is an enhancement to the previous approach which uses
bypass strictly for 2 layers.

Close overlay channels in the next HWC set phase. This allows the
framebuffer to be composed prior to the closing of channels.

When composing UI along with video, enable the overlay NOWAIT option.
If there is no UI during overlay playback, use the WAIT flag.

Update the overlay when we have a channel up. Previously, we did updates
only when the width and height changed. Now, we always update the overlay
when the channel is open, and not close the channel to update parameters
such as orientation change, flags etc.
