[PATCH 00/13 v4] perf tools: fix perf stat with large socket IDs

[James Clark]

v3 had a mistake in a couple of my signed off lines so I have fixed them
in v4.

v3 breaks up the previous v2 patchset into smaller atomic commits.
The end result is the same as the previous patchset apart from
some minor refactoring, asserting on an empty header and
calling cpu__setup_cpunode_map() in the topology self test.

Testing done:

Tested --per-core, --per-thread, --per-die, --per-node 'perf
stat' outputs on Arm ThunderX2 and Intel KNL.

Also tested 'perf stat record' and 'perf stat report --input'
with recordings from a version of perf before this patchset
to confirm that the output was the same.
