Subject: [PATCH v2 0/2] perf sched timehist: Add --show-prio & --prio option

This patch set adds --show-prio and --prio to show and filter task priorities.
Sometimes may only be interested in the scheduling of certain tasks
(such as RT tasks). Support for analyzing events of tasks with given priority(ies)
only.

Both options are disabled by default, consistent with the original behavior.

Changes since v1:
 - Rebase based on the latest perf-tools-next branch.
 - Enhance documentation's --prio entry, add a description of how to use multiple priorities. (suggested-by Namhyung)
