Adjust source code to work with giflib 5.1x

From http://giflib.sourceforge.net/gif_lib.html: GIF file openers and
closers - DGifOpenFileName(), DGifOpenFileHandle(), DGifOpen(),
DGifClose(), EGifOpenFileName(), EGifOpenFileHandle(), EGifOpen(), and
EGifClose() - all now take a final integer address argument. If
non-null, this is used to pass back an error code when the function
returns NULL.
