aa1551f299 perf test pmu: Refactor format test and exposed test APIs 
In tests/pmu.c, make a common utility that creates a PMU in a mkdtemp
directory and uses regular PMU parsing logic to load that PMU. Formats
must still be eagerly loaded as by default the PMU code assumes devices
are going to be in sysfs.

In util/pmu.[ch], hide perf_pmu__format_parse but add the eager argument
to perf_pmu__lookup called by perf_pmus__add_test_pmu. Later patches
will eagerly load other non-sysfs files when eager loading is enabled.

In tests/pmu.c, rather than manually constructing a list of term
arguments, just use the term parsing code from a string.

Add more comments and debug logging.

cd4e1efbbc perf pmus: Skip duplicate PMUs and don't print list suffix by default 
Add a PMUs scan that ignores duplicates. When there are multiple PMUs
that differ only by suffix, by default just list the first one and
skip all others. The scan routine checks that the PMU names match but
doesn't enforce that the numbers are consecutive as for some PMUs
there are gaps. If "-v" is passed to "perf list" then list all PMUs.

With the previous change duplicate PMUs are no longer printed but the
suffix of the first is printed. When duplicate PMUs are being skipped
avoid printing the suffix.

Before:

  $ perf list

d685819b40 perf pmus: Add notion of default PMU for JSON events 
JSON events created in pmu-events.c by jevents.py may not specify a
PMU they are associated with, in which case it is implied that it is
the first core PMU. Care is needed to select this for regular 'cpu',
s390 'cpum_cf' and ARMs many names as at the point the name is first
needed the core PMUs list hasn't been initialized. Add a helper in
perf_pmus to create this value, in the worst case by scanning sysfs.

v2. Add missing close if fdopendir fails.

251aa04024 perf parse-events: Wildcard most "numeric" events 
Numeric events are either raw events or those with ABI defined numbers
matched by the lexer. PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE events
should wildcard match on hybrid systems. So "cycles" should match each
PMU type with an extended type, not just PERF_TYPE_HARDWARE.

Change wildcard matching to add the event even if wildcard PMU
scanning fails, there will be no extended type but this best matches
previous behavior.

Only set the extended type when the event type supports it and when
perf_pmus__supports_extended_type is true. This new function returns
true if >1 core PMU and avoids potential errors on older kernels.

Modify evsel__compute_group_pmu_name using a helper
perf_pmu__is_software to determine when grouping should occur. Try to
use PMUs, and evsel__find_pmu, as being more dependable than
evsel->pmu_name.

Set a parse events error if a hardware term's PMU lookup fails, to
provide extra diagnostics.

this can be achieved with perf_pmus__num_core_pmus that doesn't depend
upon is_pmu_hybrid and PMU name comparisons. When modifying the
function calls take the opportunity to improve comments,
enable/simplify tests that were previously failing for hybrid but now
pass and to simplify generic code.

9d6a1df9b2 perf pmus: Allow just core PMU scanning 
Scanning all PMUs is expensive as all PMUs sysfs entries are loaded,
benchmarking shows more than 4x the cost:

```
$ perf bench internals pmu-scan -i 1000
Computing performance of sysfs PMU event scan for 1000 times
  Average core PMU scanning took: 989.231 usec (+- 1.535 usec)
  Average PMU scanning took: 4309.425 usec (+- 74.322 usec)
```

Add new perf_pmus__scan_core routine that scans just core
PMUs. Replace perf_pmus__scan calls with perf_pmus__scan_core when
non-core PMUs are being ignored.

f24ebe8053 perf pmus: Prefer perf_pmu__scan over perf_pmus__for_each_pmu 
perf_pmus__for_each_pmu doesn't lazily initialize pmus making its use
error prone. Just use perf_pmu__scan as this only impacts
non-performance critical tests.

003be8c4f7 perf stat: Make cputype filter generic 
Rather than limit the --cputype argument for "perf list" and "perf
stat" to hybrid PMUs of just cpu_atom and cpu_core, allow any PMU.

Note, that if cpu_atom isn't mounted but a filter of cpu_atom is
requested, then this will now fail. As such a filter would never
succeed, no events can come from that unmounted PMU, then this
behavior could never have been useful and failing is clearer.

336b92da1a perf tool: Move pmus list variable to a new file 
The 'pmus' list variable is defined as static variable under pmu.c file.

Introduce a new pmus.c file and migrate this variable to it. Also make
it non static so that it can be accessed from outside.
