Add rfkill.c/rfkill.h to be used for watching per-wiphy RFkill state.
It uses both /dev/rfkill and /sys because /dev/rfkill is the recommended
way of interfacing with rfkill but at the same time it doesn't provide
the information on mapping to wiphy IDs.
Note that the autoconnect_list may still contain the network. Currently
only the top entry from the list is ever used and only on
new_scan_results(), i.e. at the same time the list is being created.
If at some point it becomes part of actual device state it needs to also
be reset when a network is being forgotten.
If Disconnect is called during an ongoing connection attempt send a
CMD_DEAUTHENTICATE command same as when we're already connected, and
send a reply to potential dbus Connect call.
When a new wiphy is added, the kernel usually adds a default STA
interface as well. This interface is currently not signaled over
nl80211 in any way.
This implements a selective dump of the wiphy interfaces in order to
obtain the newly added netdev. Selective dump is currently not
supported by the kernel, so all netdevs will be returned. A patch on
linux-wireless is pending that implements the selective dump
functionality.

Instead of calling the device added or removed callback when the
interface is detected, call it when interface goes up or down. This
only affects the addition and removal of the WSC interface now.
During the network_info refactoring the adding of the connected BSS to
device->bss_list in case it is not in the scan results has moved to
after the l_hashmap_foreach_remove call meaning that the network could
be removed even though it is still pointed at by
device->connected networks. Reverse the order to what it was before.
Alternatively network_process network could take not of the fact the
network is connected and not call network_remove on it leaving it with
an empty bss_list.
It is probably rare that a disconnect should fail but if it happens the
device->state is not returned to CONNECTED and I'm not sure if it should
be, so the ConnectedNetwork property and other bits should probably be
reset at the start of the disconnection instead of at the end.
Also check if state is CONNECTED before calling network_disconnected
because network_connected may have not been called yet.
--interfaces (-i) tells iwd which interfaces to manage. If the option
is ommitted, all interfaces will be managed.
--nointerfaces (-I) tells iwd which interfaces to blacklist. If the
option is ommitted, no interfaces will be blacklisted.
