This removes dependency on tcpdump by using an already included test
tool for capturing frames with Ethernet headers. There were some issues
in getting tcpdump working on Ubuntu 19.10, so this seems to be a clean
way of addressing that.

Some of the error paths in go_neg_pbc() and go_neg_pin() did not wait
for the helper thread to complete processing. This could result in
unexpected behavior when the test case could have exited while the
thread was still performing tasks for the GO Negotiation. This could
result in getting stuck in one of the following test cases with
"go_neg_init_pbc thread caught an exception from p2p_go_neg_init: Group
formation timed out" showing up in the log.
This was hit, e.g., with the following test sequence:

This gets rid of the loop that was polling for things to do every 0.25
seconds and instead, reacts to any data from VMs as soon as it becomes
available. This avoids unnecessary operations when no new data is
available and avoids unnecessary waits when new data becomes available
more quickly.

This is more efficient since we can now start only the necessary number
of VMs instead of always forcing all VMs to start with one second delay.
This can also control the starting delay by keeping at most two VMs
starting at a time instead of using the hardcoded one second wait for
each consecutive VM.

The RECONNECT command on the station was issued immediately after
wpa_supplicant had processed EAPOL-Key msg 3/4. This could happen before
hostapd has processed EAPOL-Key msg 4/4 and especially with UML
time-travel, this could result in the following FT protocol exchange
going through in a manner that makes the hostapd process EAPOL-Key msg
4/4 from the first association as a postponed EAPOL RX at the beginning
of the second association. Avoid this by waiting hostapd to report

The previous waits were matching both DPP-TX and DPP-TX-STATUS and if

openssl engines may dynamically load external libraries. Our event_*()
functions happen to be named very generically, such that event_add()
collides with the libevent library (https://libevent.org/). This can
have disastrous effects (esp. when using CONFIG_WPA_TRACE, which enables
partial linking) when our SSL engines call into the WPS event_add()
instead of their intended libevent event_add().
Resolve this by providing a more unique prefix to these functions.
Rename performed via:
sed -i -E \
's:\<event_(add|delete_all|send_all_later|send_stop_all)\>:wps_upnp_event_\1:g' \
$(git grep -l event_)
Tested via (among other things) hwsim '-f ap_wps' module.

the recommended practice were included. The main item of some real use
