All tests which could avoid calling scan() directly have been
changed to use the 'full_scan' argument to get_ordered_network.
This was done because of unreliable scanning behavior on slower
systems, like VMs. If we get unlucky with the scheduler some beacons
are not received in time and in turn scan results are missing.
Using full_scan=True works around this issue by repeatedly scanning
until the SSID is found.
Break up the SAE tests into two parts: testSAE and testSAE-AntiClogging
testSAE is simplified to only use two radios and a single phy managed
by hostapd. hostapd configurations are changed via the new 'set_value'
method added to hostapd utils. This allows forcing hostapd to use a
particular sae group set, or force hostapd to use SAE H2E/Hunting and
Pecking Loop for key derivation. A separate test for IKE Group 20 is no
longer required and is folded into connection_test.py
testSAE-AntiClogging is added with an environment for 5 radios instead
of 7, again with hostapd running on a single phy. 'sae_pwe' is used to
force hostapd to use SAE H2E or Hunting and Pecking for key derivation.
Both Anti-Clogging protocol variants are thus tested.
main.conf is added to both directories to force scan randomization off.
This seems to be required for hostapd to work properly on hwsim.
