perf_cpu_map__new_online_cpus()
Passing NULL to perf_cpu_map__new() performs
perf_cpu_map__new_online_cpus(), just directly call
perf_cpu_map__new_online_cpus() to be more intention revealing.

pthread.h is being included for the side-effect of getting sched.h and
macros like CPU_CLR. Switch to directly using sched.h, or if that is
already present, just remove the pthread.h inclusion entirely.

If opening the event fails for basic mmap with EACCES it is more
likely permission related that a true error. Mark the test as skip
in this case and add a skip reason.

A common problem is confusing CPU map indices with the CPU, by wrapping
the CPU with a struct then this is avoided. This approach is similar to
atomic_t.
Committer notes:
To make it build with BUILD_BPF_SKEL=1 these files needed the
conversions to 'struct perf_cpu' usage:
tools/perf/util/bpf_counter.c
tools/perf/util/bpf_counter_cgroup.c
tools/perf/util/bpf_ftrace.c
Also perf_env__get_cpu() was removed back in "perf cpumap: Switch
cpu_map__build_map to cpu function".
Additionally these needed to be fixed for the ARM builds to complete:
tools/perf/arch/arm/util/cs-etm.c
tools/perf/arch/arm64/util/pmu.c

Move evsel::idx to perf_evsel::idx, so we can move the group interface
to libperf.
Committer notes:
Fixup evsel->idx usage in tools/perf/util/bpf_counter_cgroup.c, that
appeared in my tree in my local tree.
Also fixed up these:
$ find tools/perf/ -name "*.[ch]" | xargs grep 'evsel->idx'
tools/perf/ui/gtk/annotate.c: evsel->idx + i);
tools/perf/ui/gtk/annotate.c: evsel->idx);
$

As this isn't used at all in mmap.h but in evlist.h, so to cut down the
header dependency tree, move it to where it is used.
Also add mmap.h to the places using it but previously getting it
indirectly via evlist.h.
Add missing pthread.h to evlist.h, as it has a pthread_t struct member
and was getting the header via mmap.h.
Noticed while processing a Jiri's libperf batch touching mmap.h, where
almost everything gets rebuilt because evlist.h is so popular, so cut
down't this rebuild the world party.

Also we don't need to include perf_event.h in
tools/perf/lib/include/perf/evsel.h, forward declaring 'struct
perf_event_attr' is enough. And this even fixes the build in some
systems where things are used somewhere down the include path from
perf_event.h without defining __always_inline.

In the 'perf test "mmap interface"' we try creating events for several
tracepoints, but when perf_evsel__new() fails we're not showing which
one is failing, fix that to help diagnosing problems, such as the
syscall tracepoints ones being found and fixes in this merge window.
Now the failing tests shows:
# perf test -v "mmap interface"
4: Read samples using the mmap interface :
--- start ---
test child forked, pid 14311
<SNIP>
perf_evsel__new(sys_enter_getppid)
test child finished with -1
---- end ----
Read samples using the mmap interface: FAILED!
#
Now to check why the syscalls:sys_enter_getppid is failing...
# ls -la /sys/kernel/debug/tracing/events/syscalls/sys_enter_getppid
ls: cannot access '/sys/kernel/debug/tracing/events/syscalls/sys_enter_getppid': No such file or directory
