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.

Removing submapping for buffers allocated by the PmemKernelAllocator
This can be done since the restriction on multiple master maps has
been removed from the kernel

Buffers allocated from the adsp or smipool regions have a masterFd associated with each buffer.
Make sure both the fds are closed when the buffers are freed to avoid memory leaks.

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.

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.
