perf/core improvements and fixes:

. 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.
