Include the thread name along with the command name when displaying the
command name of a thread from a multi-threaded process that doesn't have
an available argument list (such as kernel processes) and threads display
is enabled via -H.

Add proper width calculation for time fields (time, cputime and usertime).
This fixes the ugly overflow in "ps aux" output for "[idle]".

Make "LOGIN" and "CLASS" columns width scale properly instead of wasting space.

Implement the usertime and systime keywords for ps, printing the
corresponding times reported by getrusage().

Export login class information via kinfo and make it possible to view
it using "ps -o class".

Correct sort order.

o) Add a keyword to displaying elapsed time in integer seconds, "etimes".
o) Give slightly better (i.e. any) documentation of the format of "etime".

[1] When showing threads, the thread name just appears if the comm
label is choosen as last printout (ucomm suffers of this such bug
too). That bug is caused by the fact that the fixed size of
printout doesn't leave enough space for them to be printed out.
Implement ucomm and comm commands with a dynamic size lenght for
buffers.

[2] On AMD64 architecture pointers don't have enough chars space to
be shown (8 chars while they need 16). Fix them by providing
a variadic space so that it fits well on both 64 and 32 bits
architectures.

Introduce a way to make pure kernal threads.
kthread_add() takes the same parameters as the old kthread_create()
plus a pointer to a process structure, and adds a kernel thread
to that process.

kproc_kthread_add() takes the parameters for kthread_add,
plus a process name and a pointer to a pointer to a process instead of just
a pointer, and if the proc * is NULL, it creates the process to the
specifications required, before adding the thread to it.

All other old kthread_xxx() calls return, but act on (struct thread *)
instead of (struct proc *). One reason to change the name is so that
any old kernel modules that are lying around and expect kthread_create()
to make a process will not just accidentally link.

fix top to show kernel threads by their thread name in -SH mode
add a tdnam formatting option to ps to show thread names.

make all idle threads actual kthreads and put them into their own idled process.
make all interrupt threads kthreads and put them in an interd process
(mainly for aesthetic and accounting reasons)
rename proc 0 to be 'kernel' and it's swapper thread is now 'swapper'

Implement the nwchan keyword that has been in the man page, but was
not implemented. This is just handy if you want to ddb the address
some process is waiting on.

When inserting a non-user-specified (e.g. not via -o or -O) format, don't dupe
one that is already there. This is consistent with GNU ps(1)'s BSD mode, and
POLA.

Conglomerate printing of ps_pgtok'd data into a PLONG type. I couldn't think
of a better name, except PINT, but I decided to go with assuming LONG to
be safe, rather than assuming INT.

Perform keyword.c:1.27 properly, implement -orss in the New World Order of
ps(1) formatting, using pgtok() to get the value in K, rather than printing
it in pages. This is consistent with behaviour before keyword.c:1.26 (et al)
which exists in STABLE today, and which uses the same metric as VSZ.

Fixed unsorting.

Use a global `now' variable for the current time, and initialise it at
startup, right after calling setlocale(3).

Implement a SUSv3-ignorant but "time"-similar format for "etime", elapsed
run time (NOT cpu time). cputime() and elapsed() both need to honour SUSv3
now.

Support the SUSv3 `rgroup' format.

Clean up some local style bogons.

SUSv3 conform on the "comm" and "args" formats, and make correct the "command"
format, since it's BSDlike, and "comm" is actually different.

Fixed unsorting.

Catch up to new priority interface.

Change the proc information returned from the kernel so that it
no longer contains kernel specific data structures, but rather
only scalar values and structures that are already part of the
kernel/user interface, specifically rusage and rtprio. It no
longer contains proc, session, pcred, ucred, procsig, vmspace,
pstats, mtx, sigiolst, klist, callout, pasleep, or mdproc. If
any of these changed in size, ps, w, fstat, gcore, systat, and
top would all stop working. The new structure has over 200 bytes
of unassigned space for future values to be added, yet is nearly
100 bytes smaller per entry than the structure that it replaced.

Introduce a 'mtxname' keyword that displays the current mutex that a
process is blocked on or '-'.

Kill #ifndef NEWVM etc. It affected a lot of other things besides
VM structure (eg: credentials etc) and it's highly unlikely we'll ever
get to see the "tainted" BSD<=4.3 VM code in public use. Although it
indicated the way some things used to be done, it obfuscates things too
much.

Dynamically adjust size of displayed username to the longest username which

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Implement a -c option to ps to display the short command name instead of
the full argument vector.

I've bumped into a few things that expected this switch to be present,
the most recent was the snmp package in ports. I'm not 100% sure of the
origins of this, but Linux has it, so does the "BSD-compatable" version
of ps on our SVR4 systems (so I assume SunOS has it too).
