 * Function:    test_multi_compat
 *
 * Purpose:     Tests the backward compatibility for MULTI driver.
 *              See if we can open files created with v1.6 library.
 *              The source file was created by the test/file_handle.c
 *              of the v1.6 library.  This test verifies the fix for 
 *              Issue 2598. In v1.6 library, there was EOA for the whole
 *              MULTI file saved in the super block.  We took it out in
 *              v1.8 library because it's meaningless for the MULTI file.
 *              v1.8 library saves the EOA for the metadata file, instead.
 *
 * Return:      Success:        0
 *              Failure:        -1
