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.

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.

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.

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.

3) Fix some format warnings. Some remain which can be fixed more easily

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.
ipcs -T' shows system information about shared memory,
message queues and semaphores. But the manual description does
not mention semapores.
Now it does.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
