Side note: this changes the semantics of read_pc to what was formerly known as read_pc_noinc. Now that memory accesses themselves can be interrupted and restarted, updating PC as a side effect is obsolete anyway.

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.
