RISC-V wants to introduce a full build of Xen without using the legacy
definitions. PPC64 has the most minimal full build of Xen right now, so make
it compile without the legacy definitions.
Mostly this is just including xen/sections.h in a variety of common files. In
a couple of cases, we can drop an inclusion of {xen,asm}/cache.h, but almost
all files get the definitions transitively.

consistency with all the other containers.
Make it non-root, use heredocs for legibility, and use the zypper long names
for the benefit of those wondering what was being referenced or duplicated.
Trim the dependencies substantially. Testing docs isn't very interesting and
saves a lot of space. Other savings come from removing a huge pile of
optional QEMU dependencies (QEMU just needs to build the Xen parts to be
useful here, not have a full GUI environment).
Finally, there where some packages such as bc, libssh2-devel, libtasn1-devel
and nasm that I'm not aware of any reason to have had, even historically.
This shaves 1G off the size of the container:
registry.gitlab.com/xen-project/xen/opensuse tumbleweed-x86_64 1.39GB
registry.gitlab.com/xen-project/xen/suse opensuse-tumbleweed 2.35GB

The history on this one is complicated. The note to README was added in
commit 1f95747a4f ("Add openssl-dev and xorg-x11-dev to README") in 2007.
At the time, there was a vendered version of Qemu in xen.git with a local
modification using <X11/keysymdef.h> to access the monitor console over VNC.
The final reference to keysymdef.h was dropped in commit 85896a7c4d ("build:
add autoconf to replace custom checks in tools/check") in 2012. The next
prior mention was in 2009 with commit a8ccb671c3 ("tools: fix x11 check")
noting that x11 was not a direct dependcy of Xen; it was transitive through
SDL for Qemu for source-based distros.
It appears there may have been other unspecified dependencies on xorg,
e.g. the use of lndir by unmodified_drivers which are no longer relevant
either.
These days its only the Debian based dockerfiles which install xorg-x11, and
Qemu builds fine in these and others without x11.

CentOS 7 is fully End-of-life as of 2024-06-30, and the Yum repo configuration
points at URLs which have become non-existent.
First, start by using a heredoc RUN for legibility. It's important to use
`set -e` to offset the fact that we're no longer chaining every command
together with an &&.
Also, because we're using a single RUN command to perform all RPM operations,
we no longer need to work around the OverlayFS bug.
Adjust the CentOS-*.repo files to point at vault.centos.org. This also
involves swapping mirrorlist= for baseurl= in the yum config.
Use a minor bashism to express the dependenices more coherently, and identify
why we have certain dependencies. Some adjustments are:
* We need bzip2-devel for the dombuilder. bzip2 needs retaining stubdom or
`tar` fails to unpack the .bz2 archives.
* {lzo,lz4,ztd}-devel are new optional dependency since the last time this
package list was refreshed.
* openssl-devel hasn't been a dependency since Xen 4.6.
* We long ago ceased being able to build Qemu and SeaBIOS in this container,
