    perf report: Create option to disable raw event ordering · 2e989f82

    Warning "dso not found" is reported when using "perf report -D".
    
     66702781413407 0x32c0 [0x30]: PERF_RECORD_SAMPLE(IP, 0x2): 28177/28177: 0x55e493e00563 period: 106578 addr: 0
      ... thread: perf:28177
      ...... dso: <not found>
    
     66702727832429 0x9dd8 [0x38]: PERF_RECORD_COMM exec: triad_loop:28177/28177
    
    The PERF_RECORD_SAMPLE event (timestamp: 66702781413407) should be after the
    PERF_RECORD_COMM event (timestamp: 66702727832429), but it's early processed.
    
    So for most of cases, it makes sense to keep the event ordered even for dump
    mode. But it would be also useful to disable ordered_events for reporting raw
    dump to see events as they are stored in the perf.data file.
    
    So now, set ordered_events by default to true and add a new option
    'disable-order' to disable it. For example,
    
      perf report -D --disable-order
    
    Fixes: 977f739b ("perf report: Disable ordered_events for raw dump")
