  perf script: Add stackcollapse.py script (2016-06-20 17:50:39 -0300)

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

New features:

. Add --dry-run option to 'perf record' to check if command line options can be
  parsed, but not doing any recording (Wang Nan)

. Allow dumping the object files generated by llvm when processing eBPF
  scriptlet events (Wang Nan)

- Add stackcollapse.py script to help generating flame graphs (Paolo Bonzini)

Documentation:

. Fix 'perf script'  documentation of '-f' when it should be '-F' (Adrian Hunter)

Infrastructure:

- Fix write_backwards fallback when using a new tool on older kernels
  without support for this feature (Arnaldo Carvalho de Melo)

- Find vdso file in cross-platform perf.data file processing scenarios (He Kuang)

- Remove some leftovers from the initial codebase copying from git
  (Arnaldo Carvalho de Melo)

- List libelf-devel as an alternative, as this is how the libelf
  development package is called on OpenSuSE (Jean Delvare)

- Rename __hists__add_entry to hists__add_entry (Jiri Olsa)
