Subject: [PATCH 12/25] perf hists browser: Move coloring logic to hpp functions
From: Namhyung Kim <namhyung.kim@....com>
Move coloring logic into the hpp functions so that each value can
be colored independently. It'd required for event group view.
For overhead column, add a callback for printing 'folded_sign' of
callchains of a hist entry.
