s390-ccw.img contains support for booting from vfio-ccw dasd passthrough
devices now, and s390-netboot.img is updated since there were changes
to the code that is shared between s390-ccw.img and s390-netboot.img.

Provide a new s390-ccw.img binary with the boot menu patches by Collin.
Though there should not be any visible changes for the network booting,
the s390-netboot.img binary has been rebuilt, too, since some of the
changes affected the shared source files.

It's already possible to do a network boot of an s390x guest with an
external netboot image based on a Linux installation, but it would
be much more convenient if the s390-ccw firmware supported network
booting right out of the box, without the need to assemble such an
external image first.
This is an s390-netboot.img that can be used for network booting.
You can download a combined kernel + initrd image via TFTP
by starting QEMU for example with:
qemu-system-s390x ... -device virtio-net,netdev=n1,bootindex=1 \
-netdev user,id=n1,tftp=/path/to/tftp,bootfile=kernel.img
Note that this version does not support downloading via config
files (i.e. pxelinux config files or .INS config files) yet. This
will be added later.
