    iterators: refactored tree iterator
    
    Refactored the tree iterator to never recurse; simply process the
    next entry in order in `advance`.  Additionally, reduce the number of
    allocations and sorting as much as possible to provide a ~30% speedup
    on case-sensitive iteration.  (The gains for case-insensitive iteration
    are less majestic.)
