Great, thanks!

Yes, in this patch - but we still want to alloc the data on the heap.

Just alloc a state struct with size of one array.

There will always be at least *one* state, so we shouldn't waste any
memory following my suggestion above.

I think you need to go through review comments for each patch
separately. In the end that might very well mean that you should
completely drop some patches, rework some and even create some some
new.

I don't think so.

Try to keep each logical change in a separate patch. That makes it
easier to review and thus also to accept patches.
