nl80211: Add driver_ops for stopping AP beaconing

Browse source 
This can be used to stop AP mode beaconing temporarily, e.g., in
response to a radar detected event.

This patch is based on the original work by Boris Presman and
Victor Goldenshtein. Channel Switch Announcement support has been
removed and event handling as well as channel set handling was
changed, among various other changes.
