MFC: Change the ABI of some of the structures used by the SYSV IPC API:

2009-07-31T20:32:55Z

- 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.

Eliminate 61 warnings emitted at WARNS=2 (leaving 53 to go).

Only warnings that could be fixed without changing the generated object code and without restructuring the source code have been handled. Reviewed by: /sbin/md5

I believe have made all of libc .c's as consistent as possible.

Fix this so that it compiles in the !STDC case.

NetBSD implements semctl using a __semctl syscall instead of the

Added SYSV ipc system calls.
