- non-device timer callbacks - machine state changing callbacks - configuration callbacks - per-screen VBLANK callbacks - DRC backend callbacks For the timer case only, I added wrappers for the old-style functions. Over time, drivers should switch to device timers instead, reducing the number of timers that are directly allocated through the scheduler.
