Catch X11 extension errors...since most of these are notifications that we
queried for a missing extension (such as the XiG vidmode one that most
people don't have), and default Xlib behaviour is to write notification to
stderr, this tends to generate incorrect bug reports.
Since we'll actually deal with the missing extension when querying for it,
we ignore these errors in our hook. The rest continue to pass through to
the default handler.
Fixes Bugzilla #42.
