  perf symbols: Fix endless loop in dso__split_kallsyms_for_kcore (2015-10-28 11:19:30 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Enable per-event perf_event_attr.inherit setting by config terms, i.e.
  this becomes possible:

      $ perf record -e cycles/inherit/ -e instructions/no-inherit/

  This affects the default, that can be changed globally using the --no-inherit
  option.

  This fine grained control appeared in the eBPF patchkit, but this added
  flexibility may end up being useful in other scenarios (Wang Nan)

- Setup pager when printing usage and help, we have long lists of options,
  better use the pager like we do with normal tooling output, i.e. when needed,
  and including any error messages in the paged output (Namhyung Kim)

- Search for more options when passing args to -h, e.g.: (Arnaldo Carvalho de Melo)

  $ perf report -h interface

   Usage: perf report [<options>]

    --gtk    Use the GTK2 interface
    --stdio  Use the stdio interface
    --tui    Use the TUI interface

- Fix reading separate debuginfo files based on a build-id, problem
  found on a Debian system (Dima Kogan)

- Fix endless loop when splitting kallsyms symbols per section for
  handling kcore files, problem found on a s390x system (Jiri Olsa)

Infrastructure:

- Prep work for the 'perf stat record' work that will allow generating
  perf.data files with counting data in addition to the sampling mode
  we have now (Jiri Olsa)
