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)
