* emu/devcb.h: Eliminated the need to call resolve() on callbacks. (#11333) Vas Crabb2023-06-171-19/+2
| | | | | | | | | | | | Read callbacks now need a default return value supplied at construction. Replaced isnull() with isunset() which tells you if the callback wasn't configured rather than whether it isn't safe to call. Enabled validation of device callbacks (it seems it was disabled at some point, probably accidentally). Device callbacks and object finders now implement the same interface for resolution.
