Make lookup nature of data structures clearer through their type. Reduce
scope of architecture specific pmu_event tables by making them static.

The pmu_events_map is generated at compile time and used for lookup. For
testing purposes we need to swap the map being used.
Having the pmu_events_map be non-const is misleading as it may be an out
argument.
Make it const and update uses so they work on const too.

the system
Add a function to find the common PMU map for the system.
For arm64, a special variant is added. This is because arm64 supports
heterogeneous CPU systems. As such, it cannot be guaranteed that the
cpumap is same for all CPUs. So in case of heterogeneous systems, don't
return a cpumap.

The mem_info struct goes to mem-events.h and branch_info goes to
branch.h, where they belong, this way we can remove several headers from
symbols.h and trim the include dependency tree more.

Move the perf_event_attr struct fron 'struct evsel' to 'struct perf_evsel'.
Committer notes:
Fixed up these:
tools/perf/arch/arm/util/auxtrace.c
tools/perf/arch/arm/util/cs-etm.c
tools/perf/arch/arm64/util/arm-spe.c
tools/perf/arch/s390/util/auxtrace.c
tools/perf/util/cs-etm.c
Also
cc1: warnings being treated as errors
tests/sample-parsing.c: In function 'do_test':
tests/sample-parsing.c:162: error: missing initializer
tests/sample-parsing.c:162: error: (near initialization for 'evsel.core.cpus')
struct evsel evsel = {
.needs_swap = false,
- .core.attr = {
- .sample_type = sample_type,
- .read_format = read_format,
+ .core = {
+ . attr = {
+ .sample_type = sample_type,
+ .read_format = read_format,
+ },
[perfbuilder@a70e4eeb5549 /]$ gcc --version |& head -1
gcc (GCC) 4.4.7
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.

The number in brackets is the offset into the raw data field of the
sample.
New functions trace_event_sample_raw__init() and s390_sample_raw() are
introduced in the code path to enable interpretation on non s390
platforms. This event bc000 attached raw data is generated only on s390
platform. Correct display on other platforms requires correct endianness
handling.
Committer notes:
Added a init function that sets up a evlist function pointer to avoid
repeated tests on evlist->env and calls to perf_env__name() that
involves normalizing, etc, for each PERF_RECORD_SAMPLE.
Removed needless __maybe_unused from the trace_event_raw()
prototype in session.h, move it to be an static function in evlist.
The 'offset' variable is a size_t, not an u64, fix it to avoid this on
some arches:
