perf/core improvements and fixes:

Infrastructure:
 
 . Do not include a struct hists per perf_evsel, untangling the histogram code
   from perf_evsel, to pave the way for exporting a minimalistic
   tools/lib/api/perf/ library usable by tools/perf and initially by the rasd
   daemon being developed by Borislav Petkov, Robert Richter and Jean Pihet.
   (Arnaldo Carvalho de Melo)
 
 . Make perf_evlist__open(evlist, NULL, NULL), i.e. without cpu and thread
   maps mean syswide monitoring, reducing the boilerplate for tools that
   only want system wide mode. (Arnaldo Carvalho de Melo)
 
 . Fix off-by-one bugs in map->end handling (Stephane Eranian)
 
 . Fix off-by-one bug in maps__find(), also related to map->end handling (Namhyung Kim)
 
 . Make struct symbol->end be the first addr after the symbol range, to make it
   match the convention used for struct map->end. (Arnaldo Carvalho de Melo)
 
 . Fix perf_evlist__add_pollfd() error handling in 'perf kvm stat live' (Jiri Olsa)
 
 . Fix python test build by moving callchain_param to an object linked into the
   python binding (Jiri Olsa)
