perf test: Introduce script for data symbol testing
The test is designed with a data structure with 64-byte alignment, it
has two fields "data1" and "data2", and other fields are reserved.
Using the "perf mem" command, we can record and report memory samples
for a self-contained workload with 1 second duration. If no samples are
obtained for the data structure "buf1", it reports failure; and by
checking the offset in structure "buf1", if the memory samples aren't
for the "data1" and "data2" fields, it means wrong data symbol parsing
and returns failure.

libperf: Propagate maps only if necessary
The current code propagate evsel's cpu map settings to evlist when it's
added to an evlist. But the evlist->all_cpus and each evsel's cpus will
be updated in perf_evlist__set_maps() later. No need to do it before
evlist's cpus are set actually.
In fact it discards this intermediate all_cpus maps at the beginning
of perf_evlist__set_maps(). Let's not do this. It's only needed when
an evsel is added after the evlist cpu/thread maps are set.

with updates at:
https://github.com/captain5050/event-converter-for-linux-perf
Updates include:
- Switch for core metrics from BDX to BDW.
- Switch for Page_Walks_Utilization to BDX version.
- Rename of topdown TMA metrics from Frontend_Bound to tma_frontend_bound.
- Addition of all 6 levels of TMA metrics. Child metrics are placed in
a group named after their parent allowing children of a metric to
be easily measured using the metric name with a _group suffix.
- ## and ##? operators are correctly expanded.
- The locate-with column is added to the long description describing
a sampling event.
- Metrics are written in terms of other metrics to reduce the

perf tools: Fix empty version number when building outside of a git repo
When perf is built in a full source tree that is not a git repository,
e.g. from a kernel source tarball, `perf version` will print empty tag
and commit strings:
$ perf version
perf version
Currently the tag version is only generated from the root Makefile when
building in a git repository. If PERF-VERSION-FILE has not been
generated and the source tree is not in a git repository, then
PERF-VERSION-GEN will return an empty version.
The problem can be reproduced with the following steps:
$ wget https://git.kernel.org/torvalds/t/linux-6.0-rc7.tar.gz
$ tar -xf linux-6.0-rc7.tar.gz && cd linux-6.0-rc7
$ make -C tools/perf
$ tools/perf/perf -v
perf version
Builds from tarballs generated with `make perf-tar-src-pkg` are not
impacted by this issue as PERF-VERSION-FILE is included in the archive.
The perf RPM provided by Fedora for 5.18+ is experiencing this problem.
Package build logs[0] show that the build is attempting to fall back on
PERF-VERSION-FILE, but it is not present.
To resolve this, revert back to the previous logic of using the kernel
Makefile version if not in a git repository and PERF-VERSION-FILE does
not exist.

Although the comment said that perhaps we need a show_tp_arg_names.
I don't think it's necessary to control them separately because it's not
so clean that part of the log shows arg names but other not.
Also when we are tracing functions it's rare to especially distinguish
syscalls and tp trace.
Only use one option to control arg names printing is more resonable and
simple. So remove the force condition and commit.

perf lock contention: Allow to change stack depth and skip
It needs stack traces to find callers of locks. To minimize the
performance overhead it only collects up to 8 entries for each stack
trace. And it skips first 3 entries as they came from BPF, tracepoint
and lock functions which are not interested for most users.
But it turned out that those numbers are different in some
configuration. Using fixed number can result in non meaningful caller
names. Let's make them adjustable with --stack-depth and --skip-stack
options.
On my setup, the default output is like below:
# /perf lock con -ab -F contended,wait_total sleep 3
contended total wait type caller
28 4.55 ms rwlock:W __bpf_trace_contention_begin+0xb

60 240.54 us rwsem:R __bpf_trace_contention_begin+0xb
27 64.45 us spinlock __bpf_trace_contention_begin+0xb
If I change the stack skip to 5, the result will be like:
# perf lock con -ab -F contended,wait_total --stack-skip 5 sleep 3

perf stat: Delay metric parsing
Having metric parsing as part of argument processing causes issues as
flags like metric-no-group may be specified later. It also denies the
opportunity to optimize the events on SMT systems where fewer events
may be possible if we know the target is system-wide. Move metric
parsing to after command line option parsing. Because of how stat runs
this moves the parsing after record/report which fail to work with
metrics currently anyway.

perf topology: Add core_wide
It is possible to optimize metrics when all SMT threads (CPUs) on a
core are measuring events in system wide mode. For example, TMA
metrics defines CORE_CLKS for Sandybrdige as:
if SMT is disabled:
CPU_CLK_UNHALTED.THREAD
if SMT is enabled and recording on all SMT threads:
CPU_CLK_UNHALTED.THREAD_ANY / 2
if SMT is enabled and not recording on all SMT threads:
(CPU_CLK_UNHALTED.THREAD/2)*
(1+CPU_CLK_UNHALTED.ONE_THREAD_ACTIVE/CPU_CLK_UNHALTED.REF_XCLK )
That is two more events are necessary when not gathering counts on all
SMT threads. To distinguish all SMT threads on a core vs system wide
(all CPUs) call the new property core wide. Add a core wide test that
determines the property from user requested CPUs, the topology and
system wide. System wide is required as other processes running on a
SMT thread will change the counts.
