hwsim tests: Allow run-tests.py to start tracing
In order to get tracing per test, allow run-tests.py to start and stop tracing per test case. This is implemented using a python 'with' context so it starts/stops automatically at the right spots. Instead of starting global tracing, also use it from run-all.sh and put the trace files into the log dir. Note that this only works right if you use a separate log dir for all test runs as the trace files aren't timestamped. Signed-hostap: Johannes Berg <johannes.berg@intel.com>
