Merge pull request #1819 in HDFFV/hdf5 from ~KOZIOL/hdf5:develop to develop

* commit '905d40aa6f6eb603c5507e7967130760e3a2e43c':
  Fix return type for H5Sselect_intersect_block().
  Updated H5TRACE macro.
  Add H5Sselect_shape_same and H5Sselect_intersect_block API routines, along with tests and minor cleanups and refactorings.
