When vary_offset is set (e.g. test case 3), the offset is not always zero so memcmpshow() will show the wrong offset in the print message. To fix this we introduce a new function memcmpshowoffset() which takes offset as a parameter and displays the right offset and use it in the case where offset is non zero. The old memcmpshow() functionality is preserved by converting it into a macro with offset preset to 0.
