This patch-set aims to reduce the amount of output printed on the terminal
when using perf sched map, allowing users to focus only on the tasks of
interest.

This helps in visualizing how a benchmark or a task is spread over
the available CPUs while also knowing which CPUs are idle(.) and which
are not(-). This will be more useful as number of CPUs increase.

Applied to perf-tools-next, thanks!
