Hmm, I think such code does exist now though (I think the Qt bindings do it?)

I'm wondering a bit if the user of libdbus should have to enable
feature extensions ... that would get pretty gross in the long term.
But the problem is that if libdbus supports fds, but the binding
doesn't, then in effect we don't support fds - but we're advertising
that we do.

We need to at least document that get_fixed_array will fail on fd arrays.
