[PATCH v3 0/5] perf stat: Fix trailing comma when there is no metric unit

[James Clark]

The first commit is failing on Arm and I think the fix should stop more
trailing comma issues which keep happening.

The second one I just noticed when looking at it. I don't feel strongly
about it so not sure if we should do it or not, but seems like the empty
metric-units exclusion from the JSON should be consistent if we're going
to have it at all.

Changes since v2:
  * Do more documentation and tidyups around struct outstate

Changes since v1:
  * Don't skip printing when the metric-unit string is empty but pass
    NULL instead of an empty string.

  perf stat: Also hide metric-units from JSON when event didn't run
  perf stat: Remove empty new_line_metric function
  perf stat: Document and simplify interval timestamps
  perf stat: Document and clarify outstate members
