  Added files:

  Introduce MAC Framework and MAC Policy entry points to label and control
  access to POSIX Semaphores:
  mac_init_posix_sem()            Initialize label for POSIX semaphore
  mac_create_posix_sem()          Create POSIX semaphore
  mac_destroy_posix_sem()         Destroy POSIX semaphore
  mac_check_posix_sem_destroy()   Check whether semaphore may be destroyed
  mac_check_posix_sem_getvalue()  Check whether semaphore may be queried
  mac_check_possix_sem_open()     Check whether semaphore may be opened
  mac_check_posix_sem_post()      Check whether semaphore may be posted to
  mac_check_posix_sem_unlink()    Check whether semaphore may be unlinked
  mac_check_posix_sem_wait()      Check whether may wait on semaphore
  Update Biba, MLS, Stub, and Test policies to implement these entry points.
  For information flow policies, most semaphore operations are effectively
