Merge sysv_msg.c:1.54, sysv_sem.c:1.71-1.72, sysv_shm.c:1.98,
msg.h:1.18:

  Second of several commits to allow kernel System V IPC data structures
  to be modified and extended without breaking the user space ABI:

  Use _kernel variants on _ds structures for System V sempahores, message
  queues, and shared memory.  When interfacing with userspace, export
  only the _ds subsets of the _kernel data structures.  A lot of search
  and replace.

  Define the message structure in the _KERNEL portion of msg.h so that it
  can be used by other kernel consumers, but not exposed to user space.

  Correct two incorrectly merged changes introduced in sysv_sem.c:1.71:
  return EINVAL rather than setting error, and don't free sops
  unconditionally.  The first change was merged accidentally as part of
  the larger set of changes to introduce MAC labels and access control,
  and potentially lead to continued processing of a request even after
  it was determined to be invalid.  The second change was due to changes
  in the semaphore code since the original work was performed.

NOTE: Change to ipcs.c in user space that catches up with kernel header
changes to follow shortly in a second commit.  The API has changed, but
not the ABI.
