  SVN rev 218492 on 2011-02-09 18:09:27Z by bschmidt
  
  Rework beacon handling re-enable run_updateslot().
  
  Drivers which rely on net80211 to create the beacon need to call
  ieee80211_beacon_update() on iv_update_beacon() calls. This is required
  that certain bits, e.g. TIM, get updated. A call to ieee80211_beacon_alloc()
  is not enough because it does not care about flags which can only change
  during runtime. By design a beacon is supposed to be allocated only once
  while moving into RUN state.
  
  To handle all possible calls to iv_update_beacon() the run_updateslot()
  function has been revived and run_updateprot() has been added.
  run_updateslot() handles slot time changes and run_updateprot() changes
  to protection, both can change while nodes associate/leave.
