PR# 39364: wpa_cli scan_results shows '0' signal level
Use rssi for level (instead of qual) in scan results, following examples
set by the wpa_supplicant ndis and iphone drivers.
- netbsd specific support
- header files
- our ioctls to get/set bssid and ssid
- use __FUNCTION__ instead of __func__
- correct handling of interfaces appearing and dissappearing, fixing
unreached code!
- debugging messages for event changes
- keep a local copy of the interface status so that we can tell if we
have notified wpa_supplicant yet about the interface change or not.
XXX: There was a byte swapping line that I commented out and I am not
sure if it is correct.
