/**
* replace_node - replace a node in a list with another one
* @old: node to be removed
* @new: node to be inserted
* update_node - update node after calling realloc on it
* @n: node to be updated
*
* Replaces node @old in the list it's linked in with node @new. Node
* @old may be a copy of the original node, which is not accessed
* through the list. The function could be called with @old == @new,
* which just fixes neighbors' pointers in the case that the node
* was reallocated.
* Fixes neighbor pointers.
