 * Function:    test_sohm_size2
 *
 * Purpose:     Tests shared object header messages using size2_helper to
 *              create different kinds of big messages.
 *
 *              If close_reopen is set, closes and reopens the HDF5 file
 *              repeatedly while writing.
 *
 *              This test works by first creating FCPLs with various
 *              parameters, then creating a standard file that includes
 *              every kind of message that can be shared using the helper
 *              function size2_helper.  The test measures the size of the
 *              file at various points.  Once all of the files have been
 *              generated, the test compares the measured sizes of the files.
