Also, remove the check for device->state == DEVICE_STATE_CONNECTING.
device_connect_cb should always called when the state is CONNECTING.
If this is not so, it indicates a bug inside the netdev layer.
This was introduced by commit f468fceb02.
However, after commit 2d78f51fac66b9beff03a56f12e5fb8456625f07, the
connect_cb is called from inside netdev_disconnect. This in turn causes
the dbus-reply to be sent out if needed. So by the time we get to the
code in question, connect_pending is always NULL.
Try to make the connect and disconnect operations look more like a
transaction where the callback is always called eventually, also with a
clear indication if the operation is in profress. The connected state
lasts from the start of the connection attempt until the disconnect.
1. Non-null netdev->connected or disconnect_cb indicate that the operation
is active.
2. Every entry-point in netdev.c checks if connected is still set
before executing the next step of the connection setup. CMD_CONNECT and
the subsequent commands may succeed even if CMD_DISCONNECT is called
in the middle so they can't only rely on the error value for that.
3. netdev->connect_cb and other elements of the connection state are
reset by netdev_connect_free which groups the clean-up operations to
make sure we don't miss anything. Since the callback pointers are
reset device.c doesn't need to check that it receives a spurious
event in those callbacks for example after calling netdev_disconnect.
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.
APShutdownTest - shutdown the AP after network connection. This
will be replaced when hwsim supports signal

InvalidPassphraseTest - Provide an invalid passphrase.
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.

Parsing of Authentication / Association management frames is not needed
since we are now using NL80211_CMD_CONNECT which combines authentication
and association into one step.
It might still be desirable to parse out authentication / association
result codes, if the result code provided in the CMD_CONNECT callback is
insufficient.
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.
Where the code just needs to find all of the network objects, don't look
for the device objects first because this only adds overhead. With
the structure now having three levels it can be even more confusing,
especially in getCurrentlyConnectedNetworkName where the outer loop
didn't check for the Device interface.
In getNetworkList don't return after the first device's networks are
listed.
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.
