  Log:
  Give timecounters a numeric quality field.
  
  A timecounter will be selected when registered if its quality is
  not negative and no less than the current timecounters.
  
  Add a sysctl to report all available timecounters and their qualities.
  
  Give the dummy timecounter a solid negative quality of minus a million.
  
  Give the i8254 zero and the ACPI 1000.
  
  The TSC gets 800, unless APM or SMP forces it negative.
  
  Other timecounters default to zero quality and thereby retain current
  selection behaviour.
