 h5dump bug 701. Symptom: The creation of a hardlink pointing to the root group "/" causes h5dump to display it as a link pointing to itself.
Cure: the root group was not being inserted in the table that keeps track of object names and links.
Added a test for this in the test generation program, the creation of a hardlink to the root
