[svn-r16707] merge 16706 from trunk
#1538 (B2) Problems with Dim Scale APIs reported by Mathworks ISSUE2: the scale index input/output parameter value passed to H5DSiterate_scales was not always incremented (it returns the scale index current iteration). SOLUTION FOR ISSUE2: modified the cycle in H5DSiterate_scales so that the scale index is always incremented TEST: added some test cases with calls to invalid indices and H5DSiterate_scales with return scale indices and visitor data tested: linux
