[PATCH v3 0/8] 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.

v3. Rebase.
v2. Don't display metric-value for json output if there is no unit.

Ian Rogers (8):
  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
  perf stat: Add metric-threshold to json output
  perf stat: Disable metric thresholds for CSV/JSON metric-only mode
