perf evlist: Allow reusing the side band thread for more purposes

I.e. so far we had just one event in that side band thread, a dummy one
with attr.bpf_event set, so that 'perf record' can go ahead and ask the
kernel for further information about BPF programs being loaded.
Allow for more than one event to be there, so that we can use it as
well for the upcoming --switch-output-event feature.

perf stat: Use affinity for opening events
...
Restructure the event opening in perf stat to cycle through the events
by CPU after setting affinity to that CPU.
This eliminates IPI overhead in the perf API.
We have to loop through the CPU in the outter builtin-stat code instead
of leaving that to low level functions.
It has to change the weak group fallback strategy slightly. Since we
cannot easily undo the opens for other CPUs move the weak group retry to
a separate loop.
Before with a large test case with 94 CPUs:
% time seconds usecs/call calls errors syscall
------ ----------- ----------- --------- --------- ----------------
42.75 4.050910 67 60046 110 perf_event_open
After:
26.86 0.944396 16 58069 110 perf_event_open
(the number changes slightly because the weak group retries
work differently and the test case relies on weak groups)
Committer notes:
Added one of the hunks in a patch provided by Andi after I noticed that
the "event times" 'perf test' entry was segfaulting.

perf record: Add a function to test for kernel support for AUX area sampling
...
Architectures are expected to know if AUX area sampling is supported by
the hardware. Add a function perf_can_aux_sample() which will determine
whether the kernel supports it.
Committer notes:
I reported that this message was taking place on a kernel without the
required bits:
# perf record --aux-sample -e '{intel_pt//u,branch-misses:u}'
Error:
The sys_perf_event_open() syscall returned with 7 (Argument list too long) for event (branch-misses:u).
/bin/dmesg | grep -i perf may provide additional information.
Adrian sent a patch addressing it, with this explanation:
----
perf_can_aux_sample_size() always returned true because it did not pass
the attribute size to sys_perf_event_open, nor correctly check the
return value and errno.
----
After applying it I get, later in the series, when --aux-sample is
added:
# perf record --aux-sample -e '{intel_pt//u,branch-misses:u}'
AUX area sampling is not supported by kernel

Will be used by 'perf trace' to support 'perf trace --filter', we need

When parse_filter() gets invoked to process --filter, it'll set the

out 'perf trace' own pid to avoid an event feedback loop, we need to
preserve the command line filter put in place by parse_filter().

perf evlist: Adopt backwards ring buffer state enum
...
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.
