When an in interface is added dynamically to hostapd with
HWSimRadio, it's not removed during device reset.
This requires to manually remove it, otherwise subsequent tests may
fail. Better do it during device reset.

Unfortunately, some objects (WlantestCapture, WpaSupplicant
and wpaspy.Ctrl) use __del__ and actually have some logic
there. This is more or less wrong, and we should be using
context managers for it. However, cleaning that up is a
pretty large task.
Unfortunately, __del__ can cause reentrant logging which is
wrong too, because it might be invoked while in the middle
of a logging call, and the __del__ of these objects closes
connections and logs while doing that.
Since we're (likely) using cpython, we can work around this
by explicitly calling gc.collect() in a context where the
logging and close is fine, not only ensuring that all the
connections are closed properly before the next test, but
also fixing the issue with reentrant logging.

The earlier change from using apdev[1] to using a no-interface
ifname=as-erp in the ERP related test cases ended up leaving the
separate authentication server interface running after the end of the
test case. This left UDP port 18128 open and any consecutive test case
needing this port failed to start another authentication server.
This can be reproduced with following test case sequence:
fils_auth_gtk_rekey authsrv_unknown_user

This seems to be needed when using python3 in VM for the ssid_utf8 test
case debug prints from the control interface requests. This breaks
python2 support for the same logging entries, but there does not seem to
be any easy way of addressing this in a manner that works for both
python versions, so move ahead with the python3-only support from now
on.

This allows more accurate logging of failures related to the cfg80211
country=98 (intersection) case. This version is trying to give some more
time to allow the country code to clear, but that does not seem to be
sufficient with the current cfg80211 implementation for country=98 (but
might be for other cases).
The additional check for country=98 at the beginning of each test case
is an attempt to force cfg80211 to restore world roaming state with a
new association and disconnection at the station side detected after the
AP side has already stopped. This is needed after the Linux kernel
commit 113f3aaa81bd ("cfg80211: Prevent regulatory restore during STA
disconnect in concurrent interfaces").

Without this, the run-tests.py socket could have been left in attached
to receive all hostapd global events during a test case. This could hit
the limit of pending messages on the socket since there is nothing
clearing this socket during the execution of a test case. Fix this by
explicitly closing the socket after having completed the RELOG command.

There were couple of common cases where the control interface for the
dynamic wpa_supplicant instance could have been left in attached state
until Python ends up cleaning up the instance. This could result in
issues if many monitor interface events were queued for that attached
socket. Make this less likely to cause issues by explicitly detaching
and closing control interfaces before moving to the next test case.
