    gal_qsort_index_arr initialized to NULL
    
    We had defined `gal_qsort_index_arr' in `lib/qsort.c', but hadn't
    initialized it. To be clean (definitely force a segmentation fault when the
    user doesn't set it), it is now initialized to NULL. It is written to be
    initialized to NULL in the comment, but apparently the actual initalization
    was forgotten.
