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.

Add support in the gralloc to specify the desired buffer size during

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 commit contains the following changes in the gralloc:
- Add buffertype in the gralloc handle i.e video buffer or UI buffer
- Add support for allocating memory from the /dev/pmem_smipool
- Add support for obtaining the buffer type and the HAL formats from the
input format which could be an OMX format.
- Add buffer type, format, width and height in the gralloc handle

libgralloc-qsd8k: Add support for non-aligned width on HDMI
While creating overlay channel for HDMI consider the aligned
width and set the crop rectangle to the actual width and height.

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

PRIV_FLAGS_NEEDS_FLUSH will trigger an ioctl call into the PMEM
driver in unlock(), so it makes not sense to set this flag for
non pmem buffers.
Change-Id: Ie1e077c10df86d3689b82fa6ce5d6c856fc95688
The purpose of this change is to add support for allocating gralloc buffers
from either /dev/pmem or /dev/pmem_adsp depending on the usage flags. It does
this by factoring out and abstracting the interactions with the pmem device.
For /dev/pmem allocations, the kernel allocator is not used, so a single master
fd is opened, and all the allocations are sub-allocated from that by gralloc.
For /dev/pmem_adsp the kernel allocator is used, so it simply opens a new fd
for each allocation.
A very basic unit test that can be run on the host is included. It requires
gtest, so to run it on a host system gtest must (currently) be compiled with
BUILD_WITH_ASTL=true.
