  Modified:    sys/i386/include  clock.h
               sys/kern  kern_clock.c
  Log:
  Improved biasing of i586 clock by adjusting for hardclock() latency.
  I decided to do this for every hardclock() call instead of lazily
  in microtime().  The lazy method is simpler but has more overhead
  if microtime() is called a lot.
  
  CPU_THISTICKLEN() is now a no-op and should probably go away.
  Previously it did nothing directly but had the side effect of
  setting i586_last_tick for CPU_CLOCKUPDATE() and i586_avg_tick for
  debugging.  CPU_CLOCKUPDATE() now uses a better method and
  i586_avg_tick is too much trouble to maintain.
  
  Reduced nesting of #includes in the usual case.
  
  Increased nesting of #includes when CLOCK_HAIR is defined.  This
  is a kludge to get typedefs for inline functions only when the
  inline functions are used.  Normally only kern_clock.c defines
  this.  kern_clock.c can't include the i386 headers directly.
  
  Removed unused LOCORE support.
