Ingo Molnar 12c1c2fd78 perf/core improvements and fixes: 
Fixes:
 
 - Support setting probes in versioned user space symbols, such as
   pthread_create@@GLIBC_2.1, picking the default one, more work
   needed to make it possible to set it on the other versions, as
   the 'perf probe' syntax already uses @ for other purposes.
   (Paul Clarke)
 
 - Do not special case address zero as an error for routines that
   return addresses (symbol lookup), instead use the return as the
   success/error indication and pass a pointer to return the address,
   fixing 'perf test vmlinux' (the one that compares address between
   vmlinux and kallsyms) on s/390, where the '_text' address is equal
   to zero (Arnaldo Carvalho de Melo)
 
 Infrastructure:
 
 - More header sanitization, moving stuff out of util.h into
   more appropriate headers and objects and sometimes creating
   new ones (Arnaldo Carvalho de Melo)
 
 - Refactor a duplicated code for obtaining config file name (Taeung Song)
