In functions parse_font_name and parse_subrs, added a test for when

loading synthetic fonts to make sure that the font name and
subrotuines are not loaded twice.  This is to remove a memory leak
that occurs because the original allocation for these objects is not
deallocated when the objects are read the second time.
