  Modified files:
    sys/sys              timetc.h 
    sys/kern             kern_tc.c 
  Log:
  Let the number of timecounters follow hz, otherwise people with
  HZ=BIGNUM will strain the assumptions behind timecounters to the
  point where they break.
  
  This may or may not help people seeing microuptime() backwards messages.
  
  Make the global timecounter variable volatile, it makes no difference in
  the code GCC generates, but it makes represents the intent correctly.
