Merge pull request #1748 in HDFFV/hdf5 from ~DEROBINS/hdf5_der:links_iterate_zero_bug to develop
* commit '0a75da70a61d41a0bf20a5c617f3eb678ed0b103':
Yanked qsort assert
Switched to HGOTO_DONE() in the links code.
Updated the HDqsort() macro to ensure we don't pass NULL buffers to qsort(3) in the future.
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.
