* Walk from current node up

* situation, its parent node would be already deflated, so it just
* needs to apply delta.
* Ensure that this node has been reconstructed and return its contents.
*
* In the worst case scenario, parent node is no longer deflated because
* we're running out of delta_base_cache_limit; we need to re-deflate
* parents, possibly up to the top base.
*
* All deflated objects here are subject to be freed if we exceed
* delta_base_cache_limit, just like in find_unresolved_deltas(), we
* just need to make sure the last node is not freed.
* In the typical and best case, this node would already be reconstructed
* (through the invocation to resolve_delta() in threaded_second_pass()) and it
* would not be pruned. However, if pruning of this node was necessary due to
* reaching delta_base_cache_limit, this function will find the closest
* ancestor with reconstructed data that has not been pruned (or if there is
* none, the ultimate base object), and reconstruct each node in the delta
* chain in order to generate the reconstructed data for this node.
