A new set of changes: 

* lots of small documentation fixes, from Jérôme Pouiller
  * beacon protection (BIGTK) support from Jouni Malinen
  * some initial code for TID configuration, from Tamizh chelvam
  * I reverted some new API before it's actually used, because
    it's wrong to mix controlled port and preauth
  * a few other cleanups/fixes
