1) hide SSID in beacon frames
 - SSID element in beacon frames will be changed to report empty (len=0)
   SSID

2) ignore clients configured with "ANY" (broadcast) SSID
 - STA f/w is asked to only reply Probe Requests that contain the SSID
   that the AP is using; especially, this means that AP does not reply
   to Probe Requests for broadcast SSID (len=0)

Testing: sniff beacon and probe messages; verify that SSID element is
removed (1) and AP is not replying to ProbeReq with broadcast SSID. In
addition, if a STA is not configured with the correct SSID, it should
not be able to associate with the AP.
