Bumping to 1.2.8 is probably a bit too new since we don't have that
version in Fedora 20, nor in RHEL-7.

It isn't unreasonable to #ifdef #else it to use the old API as an
alternative impl here. The only difference is with the old API you
had to call 'socketpair' to create the socket you pass in, instead
of getting it straight back. We can hide that difference in the
gvir_domain_open_graphics_fd method impl without trouble though.

For that matter, I'd suggest dropping the '_fd' suffix of the
method name. That's only there in libvirt because the desired
name was already taken by the old method, so we don't need to
carry over that naming.

Daniel
