perf/urgent fixes: 

- Fix finding a symbol by name when multiple maps use the same backing DSO,
   so we must first see if that symbol name is in the DSO, then see if it is
   inside the range of addresses for that specific map (Adrian Hunter)
 
 - Update the tools copies of UAPI headers, which silences the warnings
   emitted when building the tools and in some cases, like for the new
   KVM ioctls, results in 'perf trace' being able to translate that
   ioctl number to a string (Arnaldo Carvalho de Melo)
