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

User visible changes:

  * Don't try to find DSOs in SYSV maps (Don Zickus)

  * Fallback to MAP__FUNCTION if daddr maps are NULL,
    i.e. addresses get looked upon more maps (Don Zickus)

  * Kernel fix to properly handle exited tasks, by returning POLLHUP values
    on perf event file descriptors. Tooling changes will come next, but were
    tested with this kernel fix. (Jiri Olsa)

  * Add +field argument support for --field option, so that one can add
    fields to the default list of fields to show, i.e. now one can just do:

     perf report --fields +pid

    And the pid will appear in addition to the default fields. (Jiri Olsa)

Infrastructure changes:

  * More Intel PT prep stuff, including:
    - Add a 'perf test' for tracking with sched_switch
    - Add 'flush' callback to scripting API

  * hists browser (used in top and report) refactorings, getting rid of unused
    variables and reducing source code size by handling similar cases in a
    fewer functions (Namhyung Kim).

  * Explicitly include util/debug.h for powerpc, was being indirectly included,
    broke the build when some change made it stop being included. (Sukadev
    Bhattiprolu)
