This is really something tools need to do before asking for the events to be processed, leaving perf_session__process_events to do just that, process events. Also add a msg parameter to perf_session__has_traces() so that the right message can be printed, fixing a regression added by me in the previous cset (right timechart message) and also fixing 'perf kmem', that was not asking if 'perf kmem record' was ran.
