fs/shm: Add initial implementation for posix shared memory This implements the file system logic for posix shared memory: shm_open, shm_unlink, mmap, munmap and close For flat and protected builds the memory simply allocated from (user) heap For kernel build the memory is allocated from page pool and mapped with MMU This doesn't yet support protection flags or re-sizing already truncated shared memory area.
