Jukka Laitinen a0ebddaac1 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.
