  perf tools: Add snapshot format file parsing (2014-11-24 18:03:51 -0300)

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

User visible:

- Callchain improvements from Andi Kleen including:
  * Enable printing the srcline in the history
  * Make get_srcline fall back to sym+offset

- Allow to force redirect pr_debug to stderr. (Andi Kleen)

- TUI hist_entry browser fixes, including showing missing overhead
  value for first level callchain. Detected comparing the output of
  --stdio/--gui (that matched) with --tui, that had this problem. (Namhyung Kim)

- Fix segfault due to invalid kernel dso access (Namhyung Kim)

Infrastructure:

- Move bfd_demangle stubbing to its only user (Arnaldo Carvalho de Melo)

- 'perf stat' refactorings, moving stuff from it to evsel.c to use in
  per-pkg/snapshot format changes (Jiri Olsa)

- Add per-pkg format file parsing (Matt Fleming)
