Add BSS table to track scan results without dropping information
Collect information from scan results into a BSS table that will not
expire information as quickly as scan results where every new scan,
no matter for how limited set of channels/SSIDs, clears all old
information.
For now, this is only used for D-Bus BSS added/removed notifications,
but this will likely be extended to be used internally instead of the
scan results to better support partial scans.

dbus: Add an example python script for using the new dbus interface
This has example code for fetching and interface object and optionally
creating a new interface is one is not found. After that, a scan is
requested and the script continues to listed for signals from
wpa_supplicant and print information about scan results and state

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.

Move generic AP functionality implementation into src/ap
