Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

New user selectable features:

  - Support recording running/enabled time in 'perf record' (Andi Kleen)

  - New tool: 'perf data' for converting perf.data to other formats,
    initially for the CTF (Common Trace Format) from LTTng (Jiri Olsa, Sebastian Siewior)

User visible changes:

  - Only insert blank duration bracket when tracing syscalls in 'perf trace' (Arnaldo Carvalho de Melo)

  - Filter out the trace pid when no threads are specified in 'perf trace' (Arnaldo Carvalho de Melo)

  - Add 'perf trace' man page entry for --event (Arnaldo Carvalho de Melo)

  - Dump stack on segfaults in 'perf trace' (Arnaldo Carvalho de Melo)

Infrastructure changes:

  - Introduce set_filter_pid and set_filter_pids methods in the evlist class (Arnaldo Carvalho de Melo)

  - Some perf_session untanglement patches, removing the need to pass a
    perf_session instance for things that are related to evlists, so that
    tools that don't deal with perf.data files like trace in live mode can
    make use of the ordered_events class (Arnaldo Carvalho de Melo)
