qxl creates a pipe, then writes something to it to wake up the iothread from the spice server thread to raise an irq. These days qemu bottom halves can be scheduled from threads and signals, so there is no reason to do this any more. Time to clean it up. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
