  Log:
  Commit the correct copy of the g_stat structure.
  
  Add debug.sizeof.g_stat sysctl.
  
  Set the id field of the g_stat when we create consumers and providers.
  
  Remove biocount from consumer, we will use the counters in the g_stat
  structure instead.  Replace one field which will need to be atomically
  manipulated with two fields which will not (stat.nop and stat.nend).
  
  Change add companion field to bio_children: bio_inbed for the exact
  same reason.
  
  Don't output the biocount in the confdot output.
  
  Fix KASSERT in g_io_request().
  
  Add sysctl kern.geom.collectstats defaulting to off.
  
  Collect the following raw statistics conditioned on this sysctl:
  
      for each consumer and provider {
          total number of operations started.
          total number of operations completed.
          time last operation completed.
          sum of idle-time.
          for each of BIO_READ, BIO_WRITE and BIO_DELETE {
              number of operations completed.
              number of bytes completed.
              number of ENOMEM errors.
              number of other errors.
              sum of transaction time.
          }
      }
  
  API for getting hold of these statistics data not included yet.
