computing the io statistics over and over not as expensive.
This is a bit of a cop out, as I should just allocate a struct with
the computed values, but this will do for now.

option "-m io" to top(1). This allows one to identify disk bandwidth
hogs much easier.

(and not thread) scope is to be displayed, use KERN_PROC_ALL and
accrue CPU% ourselves, as the kernel makes no attempt to do so.
Of course, this doesn't make most stats any less bogus when displaying
threaded processes, but at least the CPU time is added up and not just
always 0.00%. There are still issues with SCHED_ULE in top(1) that
cause other processes to display 0.00% CPU when they in fact have used
more.

The generated manpage will now describe the actual behavior of
top(1) WRT how many processes it displays. This also eliminates
all troff(1) warnings.

fscale is a (64-bit) long. So just use a struct loadavg.
This fixes the recent failure of top on alphas:
top: sysctl(vm.loadavg...) failed: Cannot allocate memory
- use size_t for sizeof() so as to fix a few int/long warnings on alpha

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.

include:
* Mutual exclusion is used instead of spl*(). See mutex(9). (Note: The
alpha port is still in transition and currently uses both.)
* Per-CPU idle processes.
* Interrupts are run in their own separate kernel threads and can be
preempted (i386 only).

This also prevents the line-wrap and messed up display that occurs
when there happens to be one or more names with 15 chars.

seconds caused overflow. Use a type-safe but slightly slower comparison.
Comparisons for other fields are still fragile.
Fixed rounding of cputime (don't do extra work to get it slightly wrong
by first converting without rounding to milliseconds).
Removed dead code for setting cputime.
Fixed comments about cputime.

number when cpu numbers are (mis)represented.
