Since QEMU 2.10, it's possible to use a new type of display -
egl-headless which uses drm nodes to provide OpenGL support. This patch
adds a capability for that. However, since QEMU doesn't provide a QMP
command to probe it, we have to base the capability on specific QEMU
version.

For getting the reply I queried the newest and oldest QEMU using
test/qemucapsprobe.  From the differences I only extracted the reply to the new
QMP command and discarded the rest.  For all the versions below the one which
added support for the new option I used the output from the oldest QEMU release
and for those that support it I used the output from the newest one.

In order to make doubly sure the reply is where it is supposed to be (the
replies files are very forgiving) I added the property to all the replies files,
reran the tests again and fixed the order in replies files so that all the
versions are reporting the new capability.  Then removed that one property.

After that I used test/qemucapsfixreplies to fix the reply IDs.

Commit 766d5c1b deprecated the capability, because we were assuming

However since QEMU 1.5.0 (which is the earliest version we support)
we can rely on the query-command-line-options command to detect this
feature.

Let us introduce the capability vfio-ccw for supporting the basic
channel I/O passthrough, which have been introduced in QEMU 2.10. The
current focus is to support dasd-eckd (cu_type/dev_type = 0x3990/0x3390)
as the target device.

Let us also introduce the capability QEMU_CAPS_CCW_CSSID_UNRESTRICTED
for virtual-css-bridge. This capability is based on the
cssid-unrestricted property which exists if QEMU no longer enforces
cssid restrictions based on ccw device types.

Vfio-ccw capability is dependent on the hidden virtual-css-bridge, so
that we are able to probe for the cssid-unrestriced property to make
sure the devices are visible to non-mcss-e enabled guests.
