originally written in January, 2000, but have been substantially updated.
- No longer use hz/stathz and the CPU times in computing the TTY stats,
but rather use etime, like the disk stats.
- Clean up malloc/realloc failure tests.
- Use a new integrated routine to fetch devstat information via sysctl or
KVM.
- Get rid of the X() macro for calculating CPU stats
- Use rint() on the CPU state display to avoid truncation errors. (this
requires libm)
- Clean up flag usage somewhat.

crash dumps, and make it use sysctl for all data retrievals in the
"live" case (i.e. when not using iostat on a crash dump).
Remove setgid kmem for the iostat executable, it is not needed any
more after these changes.

Remove -? flag that was not working but documented. Make it work instead
but hide it in man page and usage string as others tools do.
Spelling.
Abort on allocation failure (with errx()).
o getopt returns -1 rather than EOF on errors
o getopt returns '?' for characters it doesn't know about, so
don't include them in the getopt options string.
generation was causing unaligned access faults on the Alpha.
I have incremented the devstat version number, since this is an interface
change. You'll need to recompile libdevstat, systat, iostat, vmstat and
rpc.rstatd along with your kernel.

fixed variable so all manually-specified devices are shown rather then
cutting the display off at 3, fixed formatting for msps when msps is
larger then 100 (it was blowing the columner display output before),
added -K option to make blk count (-oIK) force a 1K block size (to conform
more closely to systat, vmstat definition of blocksize).
