  Log:
  Some cleanups related to timecounters and weird ifdefs in <sys/time.h>.
  
  Clean up (or if antipodic: down) some of the msgbuf stuff.
  
  Use an inline function rather than a macro for timecounter delta.
  
  Maintain process "on-cpu" time as 64 bits of microseconds to avoid
  needless second rollover overhead.
  
  Avoid calling microuptime the second time in mi_switch() if we do
  not pass through _idle in cpu_switch()
  
  This should reduce our context-switch overhead a bit, in particular
  on pre-P5 and SMP systems.
  
  WARNING:  Programs which muck about with struct proc in userland
  will have to be fixed.
