Bring in some iostat fixes that bde reminded me about.  These fixes were
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.
