If initial bring up returns ERFKILL proceed and the inteface can be
explicitly brought up by the client once rfkill is disabled.
Also fix the error number returned to netdev_set_powered callback to be
negative as expected by netdev_initial_up_cb.
map_wiphy made the assumption that phy names follow the "phyN" pattern
but phys created or renamed by the "iw" command can have arbitrary
names. It seems that /sys/class/rfkill/rfkill%u/name is not updated on
a phy rename, so we can't use it to subsequently read
/sys/class/ieee80211/<name>/index but both
/sys/class/rfkill/rfkill%u/../index and
/sys/class/rfkill/rfkill%u/device/index point to that file.

Previously device.c would remove the whole object at the path of the
Device and the WSC interfaces but now the watches are called without the
whole object appearing and disappearing.
Change the path for net.connman.iwd.Device objects to /phyX/Y and
register net.connman.iwd.Adapter at /phyX grouping devices of the same
wiphy.
Turns out no changes to the test/* scripts are needed.
The boolean property indicates if a scan is ongoing. Only the scans
triggered by device.c are reflected (not the ones from WSC) because only
those scans affect the list of networks seen by Dbus.
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.
