A Google modification to eglCreateWindowSurface was
causing SurfaceFlinger to set its swap interval
value back to 1, regardless of the value set in the
debug.gr.swapinterval property.
This patch modifies the fb_setSwapInterval function
in gralloc to check the debug.gr.swapinterval
property and not change the swap interval if a value
is set there.

The mandate for the width and height to be even is only for the YV12
format. Add this check only for the YV12 format.

If an uncached buffer is needed from gralloc, the
client must use the flag GRALLOC_USAGE_PRIVATE_UNCACHED

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.

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

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.
