Make rt_task() return true only for RT class and add new realtime_task() to
return true for RT and DL classes to avoid some confusion the old API can
cause.
No functional changes intended in patch 1. Patch 2 changes hrtimer users as
suggested by Sebastian. Patch 3 cleans up the return type as suggested by
Steve.
Changes since v2:
* Fix one user that should use realtime_task() but remained using
rt_task() (Sebastian)
* New patch to convert all hrtimer users to use realtime_task_policy()
(Sebastian)
* Add a new patch to convert return type to bool (Steve)
* Rebase on tip/sched/core and handle a conflict with code shuffle to
syscalls.c
* Add Reviewed-by Steve
Changes since v1:
* Use realtime_task_policy() instead task_has_realtime_policy() (Peter)
* Improve commit message readability about replace some rt_task()
users.
