Wei Li <liwei391@huawei.com> reported an issue where writing PMU caps
for ARM was broken. Patch 1 addresses this issue.

Patch 2 removes unnecessary checks on a PMU's name by ensuring the
fake PMU has a name. Types are updated to have a const as a
consequence and a cleanup of the use of types is done for struct pmu's
variable name. This was motivated by the discussion:
https://lore.kernel.org/lkml/20230818171952.3719251-1-irogers@google.com/

Patches 3-5 repeat the const cleanup on struct pmu's name with the
variables id and config in struct pmu and struct parse_events_term
respectively. This is done for consistency with patch 2.

Patch 6 tidies casts around libslang and removes workarounds for
libslang support needed for a libslang older than 15 years - let's say
nobody cares about a libslang that is this old.

Ian Rogers (6):
  perf header: Fix missing PMU caps
  perf pmu: Remove logic for PMU name being NULL
  perf parse-events: Make term's config const
  perf pmu: Make id const and add missing free
  perf build-id: Simplify build_id_cache__cachedir
  perf tui slang: Tidy casts
