Actually, the only changes I have pushed to spice are those that:

- add this new spice-client-gtk.h master header
- produce a compiler #warning when including one of the sub-headers

So, at the moment, it is still possible to build virt-viewer against
both released and unreleased (git master) spice-gtk. In the latter case,
we'll just get compile warnings. This patch adds a dependency on git
master to try to avoid those warnings. But we can delay this patch and
simply live with the warnings for a little while if that's what people
prefer.
