Make the debugging printfs compile:

- printf format checking doesn't like %x for pointers; use %p like we should.
- LP64 fixes.

Add new sysctl node "KERN_SYSVIPC_INFO" with "KERN_SYSVIPC_MSG_INFO",
...
"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().

f460c85cb3
Remove existing semaphore system locking mechanism and turn
...
sys_semconfig into a placebo system call, to avoid giving folks an
easy way to wedge processes which use semaphores.
NOTE: unlike 386bsd and freebsd, processes which did not have
semaphore undo records would not be affected by this problem (reducing
it from a serious local denial-of-service problem to a largely
cosmetic problem, since virtually nobody uses semaphores). But the
code is just Wrong so we're ripping it out anyway.

__semctl13 -> ____semctl13 because this now is not called directly.

The fourth argument to it is a pointer to union semun not union semun,
because passing structs and unions to syscalls cannot be handled portably.

Overhaul of the SVID IPC facilities, primarily to use the types specified
...
by the Single UNIX Specification version 2, rather than the SVR2-derived
types. While I was here, I did a namespace sweep to expose the constants
and strucutures, and structure members described by SUSv2; documentation
updates coming shortly.
Fixes kern/8158.
