These cannot be NULL, so there is no point in checking for that. In
addition, the accessor function for this is just making the code harder
to understand.
In addition, remove Quality and Noise properties since the BSS table
is not the correct place for fetching per-channel information (Noise)
and Quality is not well-defined (nor available from many drivers).
Replace the scan results -based implementation with the use of information
from the new BSS table maintained by wpa_supplicant to get a more stable
source of BSS data. Change the use of BSSID as the key for the BSS object
to use the BSS table unique identifier so that multi-SSID APs can be
handled properly.
Must initialize key to be NULL since it can be used in an error
message. If the Scan method did not actually include any dict entries,
the uninitialized pointer was used and this could result in
wpa_supplicant crashing.
Removed the hack that used typecast to get rid of const by using local
variables that are allocated and freed. Fix couple of memory leaks
and check that the required Ifname parameter is included.
The D-Bus interface does not really have anything to do with the
wpa_supplicant ctrl_iface interface and as such, this prefix in
dbus files is both confusing and unnecessarily. Make the file names
shorter by removing this prefix.
