Soon we're going to have three types of memory pools: POSIX shm_open() pools, memfd memfd_create() ones, and privately malloc()-ed pools. Thus introduce annotations for the memory types supported and change pa_mempool_new() into a factory method based on required memory. Signed-off-by: Ahmed S. Darwish <darwish.07@gmail.com>
