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

. Fix some leaks in exit paths.

. Use memdup where applicable

. Remove some die() calls, allowing callers to handle exit paths
  gracefully.

. Correct typo in tools Makefile, fix from Borislav Petkov.

. Add 'perf bench numa mem' NUMA performance measurement suite, from Ingo Molnar.

. Handle dynamic array's element size properly, fix from Jiri Olsa.

. Fix memory leaks on evsel->counts, from Namhyung Kim.

. Make numa benchmark optional, allowing the build in machines where required
  numa libraries are not present, fix from Peter Hurley.

. Add interval printing in 'perf stat', from Stephane Eranian.

. Fix compile warnings in tests/attr.c, from Sukadev Bhattiprolu.

. Fix double free, pclose instead of fclose, leaks and double fclose errors
  found with the cppcheck tool, from Thomas Jarosch.
