5508c9dae2 perf stat: Introduce bpf_counter_ops->disable() 
Introduce bpf_counter_ops->disable(), which is used stop counting the
event.

Committer notes:

Added a dummy bpf_counter__disable() to the python binding to avoid
having 'perf test python' failing.

bpf_counter isn't supported in the python binding.

fa853c4b83 perf stat: Enable counting events for BPF programs 
Introduce 'perf stat -b' option, which counts events for BPF programs, like:

  [root@localhost ~]# ~/perf stat -e ref-cycles,cycles -b 254 -I 1000
     1.487903822            115,200      ref-cycles
     1.487903822             86,012      cycles
     2.489147029             80,560      ref-cycles
     2.489147029             73,784      cycles
     3.490341825             60,720      ref-cycles
     3.490341825             37,797      cycles
     4.491540887             37,120      ref-cycles
     4.491540887             31,963      cycles

The example above counts 'cycles' and 'ref-cycles' of BPF program of id
254.  This is similar to bpftool-prog-profile command, but more
flexible.

'perf stat -b' creates per-cpu perf_event and loads fentry/fexit BPF
programs (monitor-progs) to the target BPF program (target-prog). The
monitor-progs read perf_event before and after the target-prog, and
aggregate the difference in a BPF map. Then the user space reads data
from these maps.

A new 'struct bpf_counter' is introduced to provide a common interface
that uses BPF programs/maps to count perf events.

Committer notes:

Removed all but bpf_counter.h includes from evsel.h, not needed at all.

Also BPF map lookups for PERCPU_ARRAYs need to have as its value receive
buffer passed to the kernel libbpf_num_possible_cpus() entries, not
evsel__nr_cpus(evsel), as the former uses
/sys/devices/system/cpu/possible while the later uses
/sys/devices/system/cpu/online, which may be less than the 'possible'
number making the bpf map lookup overwrite memory and cause hard to
debug memory corruption.

We need to continue using evsel__nr_cpus(evsel) when accessing the
perf_counts array tho, not to overwrite another are of memory :-)

b214ba8c42 perf tools: Copy metric events properly when expand cgroups 
The metricgroup__copy_metric_events() is to handle metrics events when
expanding event for cgroups.  As the metric events keep pointers to
evsel, it should be refreshed when events are cloned during the
operation.

The perf_stat__collect_metric_expr() is also called in case an event has
a metric directly.

During the copy, it references evsel by index as the evlist now has
cloned evsels for the given cgroup.

Also kernel test robot found an issue in the python module import so add
empty implementations of those two functions to fix it.

8366f0d268 perf tests: Call test_attr__open() directly 
There's no longer need to call test_attr__open() from
sys_perf_event_open(), because both 'perf record' and 'perf stat' call
evsel__open_cpu(), so we can call it directly from there and not polute
the perf-sys.h header.

Committer notes:

Just like the 'verbose' variable this new 'debug_peo_args' needs to be
added to util/python.c, since we don't link the debug.o file in the
python binding, which ended up making 'perf test python' fail with:

  # perf test -v python
  18: 'import perf' in python                               :
  --- start ---
  test child forked, pid 19237
  Traceback (most recent call last):

  ImportError: /tmp/build/perf/python/perf.so: undefined symbol: debug_peo_args
  test child finished with -1
  ---- end ----
  'import perf' in python: FAILED!
  #

After adding that new variable to util/python.c:

  # perf test -v python
  18: 'import perf' in python                               :
  --- start ---
  test child forked, pid 22364

5939cacc60 perf python: Remove debug.h 
We only need to have the prototype for the eprintf() replacement we use
in the python binding, provide it and avoid dragging debug.h as a
dependency.

87ffb6c640 perf env: Remove needless cpumap.h header 
Only a 'struct perf_cmp_map' forward allocation is necessary, fix the
places that need the header but were getting it indirectly, by luck,
from env.h.

f2a39fe849 perf auxtrace: Uninline functions that touch perf_session 
So that we don't carry the session.h include directive in auxtrace.h,
which in turn opens a can of worms of files that were getting all sorts
of things via that include, fix them all.
