  perf tools: Remove xrealloc and ALLOC_GROW (2016-05-10 11:58:27 -0300)

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

User visible:

- Recording 'dwarf' callchains do not need DWARF unwinding support (He Kuang)

- Print recently added perf_event_attr.write_backward bit flag in -vv
  verbose mode (Arnaldo Carvalho de Melo)

- Fix incorrect python db-export error message in 'perf script' (Chris Phlipot)

- Fix handling of zero-length symbols (Chris Phlipot)

Andi Kleen (1):
  perf stat: Scale values by unit before metrics

Infrastructure:

- Rewrite strbuf not to die(), making tools using it to check its
  return value instead (Masami Hiramatsu)

- Support reading from backward ring buffer, add a 'perf test' entry
  for it (Wang Nan)
