"KERN_SYSVIPC_SEM_INFO" and "KERN_SYSVIPC_SHM_INFO" to return the info and data structures for the relevent SysV IPC types. The return structures use fixed-size types and should be compat32 safe. All user-visible changes are protected with #if !defined(_POSIX_C_SOURCE) && !defined(_XOPEN_SOURCE) Make all variable declarations extern in msg.h, sem.h and shm.h and add relevent variable declarations to sysv_*.c and remove unneeded header files from those .c files. Make compat14 SysV IPC conversion functions and sysctl_file() static. Change the data pointer to "void *" in sysctl_clockrate(), sysctl_ntptime(), sysctl_file() and sysctl_doeproc().
