User visible:
- Force period term to overload global settings, i.e. previously this
command line:
$ perf record -e 'cpu/instructions,period=20000/',cycles -c 1000 sleep 1
would result in both events having a period equal to 1000, with the fix we
get something saner:
$ perf evlist -v | grep period
cpu/instructions,period=20000/: ... { sample_period, sample_freq }: 20000, ...
cycles: ... { sample_period, sample_freq }: 1000 ...
$

Infrastructure:
- Use the dummy software event with freq=0 in the twatch.py python
binding example, to avoid disabling nohz (Arnaldo Carvalho de Melo)
- Add some missing constants to the python binding (Arnaldo Carvalho de Melo)
- Fix mismatched declarations for elf_getphdrnum, that happens
only in the corner case where this function is not found on
the system (Arnaldo Carvalho de Melo).
- Adding build test for having ending double slash (Jiri Olsa)
- Introduce callgraph_set for callgraph option (Kan Liang)
