Most of the refactoring looks good. One part I don't undestand.

InlineFlowBox::firstLeafChildBeforeBox looks like it used to sometimes look in
the parent, if no leaf box was found:

     if (start && !leaf && parent())
         return parent()->firstLeafChildAfterBox(this);

Likewise for lastLeafChildBeforeBox. 

It's documented that these won't return nodes outside the subtree any more, but
as a non-expert it's not clear to me why this is right. Explanation would be
appreciated.
