This is similiar with physical world, one will be surprised if the
box starts with medium exists while the tray is open.
New tests are added, tests disk-{cdrom,floppy}-tray are for the qemu
supports "-device" flag, and disk-{cdrom,floppy}-no-device-cap are
for old qemu, i.e. which doesn't support "-device" flag.
