23aadb1fcd perf callchain: Move callchain_param to util object in to fix python test 
In following commit we changed the location of callchains data:

  72a128aa08
  perf tools: Move callchain config from record_opts to callchain_param

Now all callchains stuff stays in callchain_param struct, which adds its
dependency for evsel.c object and breaks python perf.so usage
(unresolved callchain_param).

Moving callchain_param into callchain.c and adding it into
python-ext-sources unleash just another dependency hell, so I ended up
adding callchain_param into util.c for now.

Showing better error message in case we fail to open counters due to the
EBUSY error. If we detect oprofile daemon process running, we now
display following message for EBUSY error:

  $ perf record ls
  Error:
  The PMU counters are busy/taken by another profiler.
  We found oprofile daemon running, please stop it and try again.

In case oprofiled was not detected the current error message stays:

  $ perf record ls
  Error:
  The sys_perf_event_open() syscall returned with 16 (Device or resource busy) for event (cycles).
  /bin/dmesg may provide additional information.
  No CONFIG_PERF_EVENTS=y kernel support configured?

Also changing PERF_FLAG_FD_CLOEXEC detection code not to display error
in case of EBUSY error, as it currently does:

  $ perf record ls
  Error:
  perf_event_open(..., PERF_FLAG_FD_CLOEXEC) failed with unexpected error 16 (Device or resource busy)
  perf_event_open(..., 0) failed unexpectedly with error 16 (Device or resource busy)
  The PMU counters are busy/taken by another profiler.
