Merge pull request #594 in HDFFV/hdf5 from ~DEROBINS/hdf5_der:test_misc13 to develop
* commit '191147ec90d72619632a24242c003ecb3bccfffd':
* Yanked the smoke check that was recently introduced to test the unused H5I_REFERENCE ID type in test_misc19(). This fails when running testhdf5 and skipping the reference test since the H5R package won't be initialized. H5I_REFERENCE will be going away soon and the ID type is unused so there's really no point to doing anything to test it. * Cleaned up test_misc13(), which is a basic test of userblock functionality, to not emit warnings due to the large global array.
