[PATCH v2 0/6] CSV/JSON metric thresholds, fix printf modifiers

[Ian Rogers <irogers@google.com>]

Metric thresholds are being computed for CSV and JSON output but not
displayed. Rename the color that encodes the threshold as enum values
and use to generate string constants in a CSV column or json
dictionary value.

Add printf attribute to functions in color.h that could support
it. Fix bad printf format strings that this detected.

v2. Don't display metric-value for json output if there is no unit.

Ian Rogers (6):
  perf color: Add printf format checking and resolve issues
  perf stat: Fix/add parameter names for print_metric
  perf stat: Display "none" for NaN with metric only json
  perf stat: Drop metric-unit if unit is NULL
  perf stat: Change color to threshold in print_metric
  perf stat: Display metric threshold value in CSV output
