This is a newer version of tests/wnm-fuzzer tool as the initial step in
creating a more uniform set of fuzzing tools that can be used with both
libFuzzer and afl-fuzz.

It looks like the previously used sleep time was not sufficient to allow
capturing the frames from wlan0/wlan1/wlan2 to start and complete so
that all the necessary frames can be checked. This was the case
especially with UML time-travel=inf-cpu.

Recent regdb enabled UNII 3 in Finland. Change the
mbo_supp_oper_classes_fi test accordingly to accept either the previous
or the current value to be reported.

It is fine for the station to associate with either AP in this test
case, so do not force AP side connection check with apdev[0].

When the serial ports are set into raw mode on stdio (fd:0,fd:1)
then Ctrl-C is sort of passed through, but not effective. Request
non-raw mode to avoid that and let us cancel test execution with
Ctrl-C properly (both in parallel-vm.py and vm-run.sh cases).
Note that this requires a currently out-of-tree patch, but so
does the virtual time. If the patch is not applied, the command
line argument is ignored.

time-travel=inf-cpu needs bit more wait before being able to fetch the
STATUS* items after initial connection request.

Waiting for exactly one second for a one second timeout with
time-travel=inf-cpu is not exactly robust, so increase that wait to be
able to see the last EAPOL-Key TX attempt from hostapd.

Busy loop for waiting is not going to work with time-travel=inf-cpu, so
need to something a bit more explicit to wait for the wpa_supplicant
process to proceed while not fully breaking the idea of this test case
to iteration through large number of STATUS-VERBOSE commands to hit
different states.

The sae_groups parameter needs to be cleared before attempt a SAE
connection in a test case to avoid issues with this parameter having
been left to something else than the default one by a previous test
case. This was found with the following sequence:
sae_pwe_failure dpp_auto_connect_legacy_psk_sae_1

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
Fixes: e374def207 ("tests: Start ERP authentication server without AP")

This fuzzing wrapper does not go through full hostapd_clean_iface() call
to free memory, so call ap_list_deinit() to avoid reporting memory leaks
from added AP list entries. This case could not be hit with
hostapd/wpa_supplicant since they perform full interface deinit on
interface removal.

Couple of the callback functions had changed their prototypes and
p2p-fuzzer compilation resulted in a warning and not returning
*scheduled from the send_action() callback. This was reported as
use-of-uninitialized-value which was not really possible with
wpa_supplicant since the issue was only in the fuzzing wrapper.

Avoid a memory leak in fuzzer tests by calling wnm_deallocate_memory()
before exiting since this fuzzing wrapper does not use full
wpa_supplicant_cleanup().

There is no actual need for running the authentication server with
driver=nl80211, so simplify this by using driver=none instead. This
frees up apdev[1] for actual AP needs in the test cases.

This speeds up test execution significantly by removing unnecessary
waiting for things to happen since the kernel log is allowed to jump
forward whenever there is nothing to do.

This test case was failing frequently due to the station not being able
to connect back to the AP if the interrupted channel switch ended up
moving the AP to the new channel anyway on restart. Scan both possible
channels to allow the AP to be found in either case.

These cases are for the IEEE 802.11 Status Code and Reason Code and
those fields are unsigned 16 bit values, so use the more appropriate
type consistently. This is mainly to document the uses and to make the
source code easier to understand.
