rtirq update - 2018 edition

Hi there!

Almost 3 years after the last time, rtirq has been updated!

No big deal whatsoever just that scheduling policies and priorities are now reset/stop to SCHED_FIFO and 50, respectively. In fact there's no urge to update at all; the previous versions are still good to have around ;) It's just that things get a bit more politely correct on "reset" and/or "stop" modes.

The original packages available here:

nb. the rtirq init-script/systemd-service only makes sense on real-time preemptive (PREEMPT_RT) or threadirqs enabled GNU/Linux kernels.

Cheers && Enjoy!
