sys-process/rtirq: Initial commit. A crucial part of professional realtime audio is low latency. rtirq sets realtime priorities and scheduling policies for desired IRQ threads on boot. Without rtirq you would need to set these priorities yourself after each boot or live with sound dropouts. See also [1].
