hostapd: Add a database of neighboring APs Add a configurable neighbor database that includes the content of Nighbor Report element, LCI and Location Civic subelements and SSID. All parameters for a neighbor must be updated at once; Neighbor Report element and SSID are mandatory, LCI and civic are optional. The age of LCI is set to the time of neighbor update. The control interface API is: SET_NEIGHBOR <BSSID> <ssid=SSID> <nr=data> [lci=<data>] [civic=<data>] To delete a neighbor use: REMOVE_NEIGHBOR <BSSID> <SSID> Signed-off-by: David Spinadel <david.spinadel@intel.com>

hostapd: Add FTM range request Add FTM range request via RRM. The AP sends Radio measurement request with FTM range request as a request for the receiving STA to send FTM requests to the given list of APs.
