perf/core improvements and fixes:

Browse source 
User visible:
 
 - Properly report when a function wildcard produces no matches in 'perf probe'
   (Masami Hiramatsu)
 
 - Balance opening and reading events in 'perf stat', which could cause
   it to get stuck trying to close invalid file descriptors (Mark Rutland)
 
 Infrastructure:
 
 - Copy more headers from the kernel, this time for headers that
   were just including the contents of its kernel counterparts, should
   help resolving the problems with linux-next, where some uapi related
   patches seem to be breaking tools/object/ build.
 
   Some more combing will be done, but at least it is possible to build
   perf out of tree, via a detached tarball (make help | grep perf)
   without including kernel files in its MANIFEST (Arnaldo Carvalho de Melo)
 
 - Fix smatch found errors that were not causing problems, but are
   mistakes nonetheless (Dan Carpenter)
 
 - Fix string vs byte array resolving in the python script code (Jiri Olsa)
