 * Function:    test_copy_cdt_merge_cdt
 *
 * Purpose:     Tests the "merge committed datatypes" feature of H5Ocopy:
 *        SRC file:
 *            Create committed datatype (short)
 *            Create committed datatype (float)
 *            Create committed datatype (int), with attribute of ndt int
 *            Create committed datatype (double), with attribute of anon ndt short
 *        DST file:
 *            Create committed datatype (int)
 *            Create committed datatype (float), with attribute of native int
 *            Create committed datatype (double), with attribute of anon ndt short
 *
 *        Copy / at SRC to DST
 *        Verify that committed datatypes are copied and merged correctly
 *
 *        NOTE:
 *          Comparison of attributes are not implemented yet.
 *          Further tests will be added in the future.
 *
 * Return:      Success:        0
 *              Failure:        number of errors

/*-------------------------------------------------------------------------
 * Function:    test_copy_dataset_open
 *
 * Purpose:     To ensure that H5Ocopy() copies data of opened dataset correctly.
 *        This is for bug fix HDFFV-7853.
 *
 *        Test Case 1:
 *        Create a dataset with attributes in SRC file
 *        Copy the opened dataset to another location in the same file
 *        Copy the opened dataset to DST file
 *        Close the dataset
 *
 *        Test Case 2:
 *        Reopen the dataset, write new data to the dataset
 *        Copy the opened dataset to another location in the same file
 *        Copy the opened dataset to to DST file
 *        Close the dataset
 *
 *        Test Case 3:
 *        Create a committed datatype
 *        Create a dataset with the committed datatype in SRC file
 *        Open the committed datatype
 *        Copy the opened dataset (with the opened committed datatype) to another location in the same file
 *        Copy the opened dataset (with the opened committed datatype) to DST file
 *        Close the dataset and the committed datatype
 *
 *        Test Case 4:
 *        Create a group with attributes, create a dataset in the group
 *        Copy the opened group (together with the opened dataset) to another location in the same file
 *        Copy the opened group (together with the opened dataset) to DST file
 *        Close the group and the dataset
 *
 * Return:      Success:        0
 *              Failure:        number of errors

    /* close property list.
     * NOTE: if this property list is not closed and the test is
     *          run with the split or multi driver, an interesting
     *          problem is exposed in the property list shutdown code.
     *
     *          Namely, since the split/multi driver copies property
     *          lists for internal use, there's a (high) chance that
     *          leaving the FAPL open and having the library's shutdown
     *          code close it will cause the underlying property lists
     *          to be cleaned up first, causing the actual property list
     *          close operation to fail (since it won't be able to close
     *          the already closed underlying property list).
     *
     *          The could be addressed by converting the split/multi to
     *          use non-public API routines, or putting some way into the
     *          public H5I routines to indicate ordering at shutdown.
     *
     *          For now, we just make certain to close the property list.
