 into perf/urgent

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

python interface fixes:

- Make 'perf script -g python' generate scripts that are compatible
  with both python 2 and 3 (Jeremy Cline)

- Fix python dictionary reference counting (Janne Huttunen)

- Add python3 support for various python scripts (Jeremy Cline)

- Use python-config --includes rather than --cflags, fixing the build
  on Fedora, where the python 3.7 started adding -flto to what

perf stat fixes:

  - Remove needless extra header line in --interval_clear (Jiri Olsa)
  python-config --cflags generate, breaking the perf build (Jeremy Cline)

Build fixes:

- Fix compilation errors on gcc8 (Jiri Olsa)

perf llvm-utils fixes:

- Remove bashism from kernel include fetch script (Kim Phillips)

perf test fixes: (Kim Phillips)

- Replace '|&' with '2>&1 |' to work with more shells

- Make perf's inet_pton test more portable

- Prevent temporary editor files from being considered test scripts
