MFC: Change the ABI of some of the structures used by the SYSV IPC API:
- Various members of struct ipc_perm use appropriate types instead of
  unsigned short.
- The shm_segsz member of struct shmid_ds is now a size_t instead of an
  int which should allow for complete support of SYSV SHM regions >= 2GB.
- The shm_nattch member of struct shmid_ds is now an int instead of a
  short.
- The existing versions of the __semctl(), msgctl(), and shmctl() system
  calls have been renamed to freebsd7_*() and implement the old ABI. New
  versions of these system calls provide the new ABI.  The new system
  calls also use newer symbol versions in libc so old and new binaries
  will both work under new kernels.
- Specific to 7.x: the kern_msgctl(), kern_semctl(), and kern_shmctl()
  functions now use ABI shims that transparently "rename" the functions
  to kern_new_*() for all new modules.  Existing compat functions under
  the old names remain to provide compatibility for older kernel modules.
