42c6d72977 libgralloc-qsd8k: Remove submaps for PmemKernelAllocators
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

06304d437b Align pmem for NV12 Tiled buffers
The decoder requires the NV12Tiled buffers to be physically aligned to 8k.

3be64f08f9 libgralloc-qsd8k: Close the masterFd when freeing video/camera buffers
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.

d1fc805f34 libgralloc-qsd8k: Initial gralloc changes for honeycomb
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

5bc176b1a6 Refactor the qsd8k gralloc implementation.
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.
