Various build/boot bots have reported WARNs being triggered by the ARM

This boils down to two instances of right-shifting a 32-bit unsigned

It isn't possible to get the stack of a running task (other than
current) because we don't have the stack pointer and the stack can be
inconsistent anyway. Add a safe stack saving facility which only saves
the stack of the task if it's sleeping or if it's the current task.

Add a sched_task_call() to allow a callback function to be called with

or inactive during the function call, without having to expose rq
