configtree: T4235: distinguish sub(-tract) tree from delete tree
The DiffTree class maintains both the 'sub'(-tract) configtree,
containing all paths in the LHS of the comparison that are not in the
RHS, and the 'delete' configtree: the delete tree is the minimal subtree
containing only the first node of a path not present in the RHS. It is
the delete tree that is needed to produce 'delete' commands for config
mode, whereas the 'sub' tree contains full information, needed for
recursively detecting changes to a node.
