Since fb_post and dequeueBuffer may be called
from different threads, it might happen
that both wait for available buffer causig
both threads to go in sleep. To solve this
problem we add lockBuffer implementation
and remove waits from fb_post and dequeueBuffer.
This will also be consistent with native window
implementation.

Add a fallback mechanism to allocate memory from ashmem if pmem
allocation fails.
Do not fallback in the following cases:
- MDP composition is being used.
- Client has explicitly requested that the memory be allocated from
pmem.
- Buffer will not be sent to the overlay.

Add support for the GRALLOC_USAGE_EXTERNAL_DISP and the
GRALLOC_USAGE_PROTECTED usage bits. If any of the two usage bits are
set, we need to send the buffers to the overlay.
Since we send the buffers to the overlay, we need to allocate these
buffers from the PMEM region.

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.

For portrait mode: Actionsafe width depends on actionsafe
height, thus maintaining the aspect ratio.
User entered value for actionsafe width doesn't matter.
For landscape mode: Both, user entered actionsafe width
and height matter. Aspect ratio may change, in an attempt to fill
up the TV screen till the edges to avoid overscan/underscan.

this wouldn't make sense, since the h/w wouldn't be able
