The code would assume that a command with argc >= 3 would always be
composed of <family name> <entity> <command> and thus
"known-networks forget <ssid>" could not be executed. Instead of
checking argc >= 3 check whether command->entity is non-NULL.
Add ObjectManager objects with properties for each Known Network so that
signals are emitted for creation or removal of a Known Network and a
Property Changed is emitted on LastConnectedTime change. Remove the
ListKnownNetworks method from the old KnownNetworks interface.
Note this breaks clients that used the known networks interface.
Drop the corresponding network_info field, function and D-Bus property.
The last seen times didn't seem useful but if a client needs them it can
probably implement the same logic with the information already available
through DBus.
If the sm object (or the handshake object) is NULL, don't call the
corresponding function.

This allows to inspect the cmd line for the existence of a provided
token. This enables the completers to look back to what was entered
before them and make decisions based on that information. For
example, this can be used in completion of the property values
to identify the property for which the value is being completed.
Until now network.c managed the list of network_info structs including
for known networks and networks that are seen in at least one device's
scan results, with the is_known flag to distinguish known networks.
Each time the list was processed though the code was either interested
in one subset of networks or the other. Split the list into a Known
Networks list and the list of other networks seen in scans. Move all
code related to Known Networks to knownnetworks.c, this simplifies
network.h. It also gets rid of network_info_get_known which actually
returned the list of all network_infos (not just for known networks),
which logically should have been private to network.c. Update device.c
and scan.c to use functions specific to Known Networks instead of
filtering the lists by the is_known flag.
This will also allow knownnetworks.c to export DBus objects and/or
properties for the Known Networks information because it now knows when
Known Networks are added, removed or modified by IWD.
The return value from network_connected is not checked and even if one
of the storage operations fails the function should probably continue
so only print a message on error.
If the device mode it toggled from 'ap' back to 'station' without actually
starting the access point ap_free attempts to zero out the psk, which
causes a crash because it had never been allocated (Start() never was
called). Since ap->psk is actually never used this was removed. Also added
a memset to zero out the pmk on cleanup.
This is the crash observed:
