  Modified files:
    sys/i386/conf        files.i386 
    sys/i386/include     clock.h 
    sys/i386/isa         clock.c random_machdep.c

  Removed files:
    sys/i386/i386        microtime.s 
  Log:
  Replace TOD clock code with more systematic approach.
  
  Highlights:
      * Simple model for underlying hardware.
      * Hardware basis for timekeeping can be changed on the fly.
      * Only one hardware clock responsible for TOD keeping.
      * Provides a real nanotime() function.
      * Time granularity: .232E-18 seconds.
      * Frequency granularity:  .238E-12 s/s
      * Frequency adjustment is continuous in time.
      * Less overhead for frequency adjustment.
      * Improves xntpd performance.
