cairo: 1.16.0 -> 1.18.0

- libiconv and expat are no longer used.
- libintl and xcbutil no longer appear to be used.
- The GL backend has been removed.
- We can no longer disable PDF support, since something always
propagates zlib.
- Not sure whether the Requires.private is still needed, so I've left
it.

       Cairo is a 2D graphics library with support for multiple output
       devices.  Currently supported output targets include the X
-      Window System, Quartz, Win32, image buffers, PostScript, PDF,
-      and SVG file output.  Experimental backends include OpenGL
-      (through glitz), XCB, BeOS, OS/2, and DirectFB.

       Cairo is designed to produce consistent output on all output
