perf/core improvements and fixes: 

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 ...
  $
 
  (Jiri Olsa)
 
 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)
