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. Change-Id: If2ae0151698fad8107e18e808a3fa012a846263f
