Konstantin Belousov 940cb0e2bb Implement read(2)/write(2) and neccessary lseek(2) for posix shmfd. 
Add MAC framework entries for posix shm read and write.

Do not allow implicit extension of the underlying memory segment past
the limit set by ftruncate(2) by either of the syscalls.  Read and
write returns short i/o, lseek(2) fails with EINVAL when resulting
offset does not fit into the limit.
