auto-t: test for temporary blacklist The simplest way to test this was to create a new AP, where max_num_sta=1. This only allows a single STA to connect to this AP. We connect a device to this AP, then try and connect with another. This results in hostapd failing with DENIED_NO_MORE_STAS, which will cause a temporary blacklist. We can then disconnect both devices, and reconnect the device that previously got denied. If it connects then we know the blacklist only persisted for that earlier connection.

auto-t: updated autotests to use hwsim.get_radio This removes all the duplicated code where the interfaces are iterated and the radio/hostapd instances are created. Instead the two new APIs are used to get each instance, e.g.: hapd = HostapdCLI(config='ssid.conf') radio = hwsim.get_radio('radX')

auto-t: fix testBSSBlacklist There were a number of fixes here. The waits were changed to wait on the device state instead of the network state and hwsim rules were removed after the test as to not interfere with future tests. One of the rules was setting the signal to -10000 wich was causing the ranking to be zero.
