Fixed a bug in the links code where iterating over an empty group would
pass a NULL pointer to qsort(3), which is undefined behavior. Fixes HDFFV-10829

+ - When iterating over an old-style group (i.e., when not using the latest
+ file format) of size 0, a NULL pointer representing the empty links
+ table would be sent to qsort(3) for sorting, which is undefined behavior.
+
+ Iterating over an empty group is explicitly tested in the links test.
+ This has not caused any failures to date and was flagged by gcc's
+ -fsanitize=undefined.
+
+ The library no longer attempts to sort an empty array.
