Log:
  Add CTLFLAG_STATS to sysctl flags
  
  In preparation for sysctl(8) growing the ability to only print
  out boot/run-time tunables we need a way to differentiate between
  RW sysctl nodes that tune a particular thing, or simply export
  a stat that we want to allow the sysadmin to reset to 0 (or some
  other value).
  
  To do so, we add the CTLFLAG_STATS which should be OR'd into the
  CTLFLAGs when exporting a "writable/resettable" statistic node via
  sysctl.
