49f8bb9a95 Fix printing of shared memory limits.

55e2cb41f2 Add the ability to clean up all shared memory segments which are
unused in one go.

From the original PR:

	I've observed that linux apps running under the linuxulator
	have a habit of leaving behind shared memory segments which
	are unused, but which eventually cause the system to run
	out of free segments and these apps will stop working.
	ipcrm(1) currently only allows removal of unused message
	queues, shared memory segments and semaphores on an individual
	basis, or those having a matching (non-zero) key. However
	it would often be convenient to just do a complete cleanup
	of everything, usually as root.

fa44a2923e Stylify ipcs/ipcs.c and ipcrm/ipcrm in preparation of the upcoming
changes as proposed in bin/118292.

Feel free to mention any I have missed, there is much to learn with
regarding to style(9).

9baea4b4b4 Change the data type of the upper shared memory limits from a signed
integer to an unsigned long. This lifts variables like the maximum
number of pages available for shared memory from 2^31 to 2^32 on 32
bit architectures, and from 2^31 to 2^64 on 64 bit architectures.

It should be noted that this changes breaks ABI on 64 bit architectures
because the size of the shmmax, shmmin, shmmni, shmseg and shmall members
of the shminfo structure has changed.

701fabc74b If sysctlbyname fails for kernel related reasons, tag the errno
string to the end of the error message. I think we used errx()
there when we really wanted an err().

336c393fc0 Use 12 columns for (int) values, 20 columns for (long) and align
headers properly (right justified for numbers, left justified for
everything else).

This fixes the alignment of the fields on i386, sparc64 and amd64
today but does not dynamically assign column widths or bear in mind
that some of the values may be 64-bit in the future.

75d6abdb7e third of several commits to allow kernel System V IPC data structures
to be modified and extended without breaking the user space ABI:

Make the "ipcs" tool, which grubs around in kernel memory to report
status relating to System V IPC, use the _kernel variants on the
System V IPC data structures.

76e46948d7 1) Add missing prototypes for fmt_perm and cvt_time.
2) Move a break outside a #if block to keep gcc3 from seeing a "default:"
   at the end of a block.
3) Fix some format warnings. Some remain which can be fixed more easily
   when we have a full C99 printf.

c447342094 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.
