  SVN rev 209053 on 2010-06-11 17:03:26Z by mdf
  
  Add INVARIANTS checking that numfreebufs values are sane.  Also add a
  per-buf flag to catch if a buf is double-counted in the free count.
  This code was useful to debug an instance where a local patch at Isilon
  was incorrectly managing numfreebufs for a new buf state.
