    sys/sys              msg.h sem.h shm.h 
  Merge msg.h:1.17, sem.h:1.28, shm.h:1.20 from HEAD to RELENG_5:
    First of several commits to allow kernel System V IPC data structures
    to be modified and extended without breaking the user space ABI:
    Define _kernel wrapper data structures for the user-exposed data
    structures that current server as the internal data structures for
    the implementation:
    - struct msqid_kernel wraps struct msqid_ds.
    - struct semid_kernel wraps truct semid_ds.
    - struct shmid_kernel wraps struct shmid_ds.
    - Don't expose extern definition 'shmsegs' outside of sysv_shm.c.
