Ah, an iterator. Yes, it would allow switching from iteration on scan
lines to iteration on actual dirty ranges.
Perhaps
void memory_region_for_each_dirty_range(MemoryRegion *mr,
target_phys_addr_t start,
uint64_t size,
void (*dirty)(void *opaque,
target_phys_addr_t start, uint64_t size),
void *opaque);

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.
