I'm afraid this commit will have to be reverted as it completely
disables copy&paste from client to guest:
According to the GTK+ docs, gtk_clipboard_get_owner() corresponds to
the owner object set by gtk_clipboard_set_with_owner().
So if another application in the client's system grabs the clipboard,
spice-gtk receives "owner-change" event, gtk_clipboard_get_owner()
returns NULL and the callback returns without sending a grab to the
vdagent.
Cheers,
Jakub
