perf/core improvements and fixes 

. Fix hardware cache event name generation, fix from Jiri Olsa
 
 . Add round trip test for sw, hw and cache event names, catching the
   problem Jiri fixed, after Jiri's patch, the test passes successfully.
 
 . Clean target should do clean for lib/traceevent too, fix from David Ahern
 
 . Check the right variable for allocation failure, fix from Namhyung Kim
 
 . Set up evsel->tp_format regardless of evsel->name being set already,
   fix from Namhyung Kim

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

 - Rename libtraceevent 'private' struct member to 'priv' so that it works
   in C++, from Steven Rostedt

 - Remove lots of exit()/die() calls from tools so that the main perf exit
   routine can take place, from David Ahern

 - Fix x86 build on x86-64, from David Ahern.

 - Remove some headers that prevented perf from building on Android,
   from David Ahern

 - {int,str,rb}list fixes from Suzuki K Poulose

 - perf.data header fixes from Namhyung Kim

 - Replace needless mempcpy with memcpy, to allow build on Android, from Irina Tirdea

 - Allow user to indicate objdump path, needed in cross environments, from
   Maciek Borzecki

 - Fix hardware cache event name generation, fix from Jiri Olsa

 - Add round trip test for sw, hw and cache event names, catching the
   problem Jiri fixed, after Jiri's patch, the test passes successfully.

 - Clean target should do clean for lib/traceevent too, fix from David Ahern
