One batch of changes, containing: 

* hwsim improvements from Jouni and myself, to be able to
    test more scenarios easily
  * some more HE (802.11ax) support
  * some initial S1G (sub 1 GHz) work for fractional MHz channels
  * some (action) frame registration updates to help DPP support
  * along with other various improvements/fixes
