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.

- Remove unused GRALLOC_USAGE_PRIVATE_PMEM flag. This flag is no
longer used.
- Flush ashmem region cache instead of Invalidating it.

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

- Stagefright no longer sends the OMX Formats to the gralloc, remove
unnecessary code from the function.
- Add support for the YV12 format in getGrallocInformationFromFormat

Add support in the gralloc to specify the desired buffer size during
buffer allocation. This is done via a new function in the gralloc(allocSize).
If the specified size is lesser that the calculated size,
set the buffer size to the calculated size.

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.

Add support for Side-by-Side full, Side-By-Side-half formats in the overlay.
The Side by Side half formats could either be in Left-Right or Right-Left mode.

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
to use the buffer. in this case it it better to fail to
let the caller a change to try again with different usage bits.

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.
