The need stems from my testing python bindings for these new APIs that
I'm writing. When I call the restore API with no arguments, which is
equivalent to calling plain virDomainRestoreParams(conn, NULL, 0, 0);
then I see the following error:

libvirt: QEMU Driver error : Failed to open file '(null)': Bad address

Obviously, this is wrong. And indeed, when I think about the API more
then the path to restore from is critical, at least for now. But as I
suggests in one of my previous replies, I'm going to make path required
in typed params for now. If we ever come with an alternative source for
restore then that check can be relaxed.
