auto-t: prepare autotests for test-runner re-write The tests basically remained the same with a few minor changes. The wiphy_map and in turn hostapd_map are no longer used. This was already partially converted a long time ago when the 'config' parameter was added to HostapdCLI. This patch fully converts all autotests to use 'config' rather than looking up by interface. Some test scripts were named 'test.py' which was fine before but the new rewrite actually loads each python test as a module. The name 'test' is too ambiguous and causes issues due to a native python module with the same name. All of these files were renamed to 'connection_test.py'.

autotests: Test communication when iwd reports connected Test that the AP interface and the station interface managed by iwd can actually send and receive ethernet traffic when iwd is in the connected state. Due to linux routing none of the high level utilities like ping or arping can be easily used to test communication between two interfaces of the same machine so use a method based on the mac80211_hwsim/tools/hwsim_test.c utility in the wpa_supplicant tree that uses a raw socket to inject unicast and broadcast frames. Add this check in three tests of different security type connections that simulate a single AP, and the two roaming tests with two APs. Check that the station can't communicate with the other AP's interface.

auto-t: update roaming tests with wait_for_object_change Every single roaming test had one of two problems with watching the state change between roaming --> connected. Either the test used wait_for_object_condition to wait for 'connected' which could allow other states in between. Or it simply used an assert. The assert wouldn't allow other state changes, but at the cost of potentially failing due to IWD not having made it to the 'connected' state yet. Now we have wait_for_object_change which takes two conditions: initial (from_str) and expected (to_str). This API will not allow any other conditions except these, and will wait for the expected condition before continuing. This allows roaming test to reliably wait for the roaming --> connected state change.
