    perf tools: Stop using a global trace events description list · da378962
    Arnaldo Carvalho de Melo authored
    The pevent thing is per perf.data file, so I made it stop being static
    and become a perf_session member, so tools processing perf.data files
    use perf_session and _there_ we read the trace events description into
    session->pevent and then change everywhere to stop using that single
    global pevent variable and use the per session one.
    
    Note that it _doesn't_ fall backs to trace__event_id, as we're not
    interested at all in what is present in the
    /sys/kernel/debug/tracing/events in the workstation doing the analysis,
    just in what is in the perf.data file.
    
    This patch also introduces perf_session__set_tracepoints_handlers that
    is the perf perf.data/session way to associate handlers to tracepoint
    events by resolving their IDs using the events descriptions stored in a
    perf.data file. Make 'perf sched' use it.
