ae0ead8db3 fix semaphore ID bound checking 
problem pointed and patch provided in kern/23585 by Jeff Ito

2e59e9ae06 allocate virtual memory for SYSV shm, msg and semaphore structures 
separately from the bufpages, so that it would be possible to eventually
make their limits changeable in runtime

make static all local variables which do not need to be exported to other
kernel parts

d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage, 
and need to be examined and discussed more.

960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can 
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

3f0d660168 Make the debugging printfs compile: 
- printf format checking doesn't like %x for pointers; use %p like we should.
 - LP64 fixes.

38cc1b3975 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.

3cbe025990 __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.

dc8ecaa15b 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.
