Preparation for hiding pmu_events_map as an implementation detail. While
the map is passed, the table of events is all that is normally wanted.
While modifying the function's types, rename pmu_events_map__find to
pmu_events_table__find to match later encapsulation. Similarly rename
pmu_add_cpu_aliases_map to pmu_add_cpu_aliases_table.

pmu_events_map has a type variable that is always initialized to "core"
and a version variable that is never read. Remove these from the API as
it is straightforward to add them back when necessary.

Rather than export test functions, export the test struct. Rename with a
suite__ prefix to avoid name collisions.
Committer notes:
Its '&suite__vectors_page', not '&suite__vectors_pages', noticed when
cross building to arm (32-bit).

parse_events() may succeed but leave string memory allocations reachable
in the error.
Add an init/exit that must be called to initialize and clean up the
error. This fixes a leak in metricgroup parse_ids.

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.

I found that the UNHALTED_CORE_CYCLES event is only available in the
Intel machines and it makes other vendors/archs fail on the test. As
libpfm4 can parse the generic events like cycles, let's use them.
