Our support for Xen lacks maintenance and since Xen has monthly security
advisories it is reasonable to assume our version is affected by a
multitude of security problems that are fixed upstream.
How many advisories? Browsing oss-security shows the following number of
advisories in each of the following years:
2022: 3
2021: 53
2020: 54
2019: 46 <-- we are *here*

This commit adds the xen_4_8 package to be used instead of
xen (currently at 4.5.5):
* Add packages xen_4_8, xen_4_8-slim and xen_4_8-light
* Add packages qemu_xen_4_8 and qemu_xen_4_8-light to be used
with xen_4_8-slim and xen_4_8-light respectively.
* Add systemd to buildInputs of xen (it is required by oxenstored)
* Adapt xen service to work with the new version of xen
* Use xen-init-dom0 to initlilise dom0 in xen-store
* Currently, the virtualisation.xen.stored option is ignored
if xen 4.8 is used
Recent commit #c10af9e744c91dff1ccc07a52a0b57d1e4d339f3 changed the
behaviour of wrapPythonPrograms, which caused pygrub to no longer
being wrapped. This commit fixes this.
Also:
* provides a bunch of build options
* documents build options config in longDescription
* provides a bunch of predefined packages and documents them some more
* sources' hashes stay the same
The following parameters are now available:
* hardeningDisable
To disable specific hardening flags
* hardeningEnable
To enable specific hardening flags
Only the cc-wrapper supports this right now, but these may be reused by
other wrappers, builders or setup hooks.
cc-wrapper supports the following flags:
* fortify
* stackprotector
* pie (disabled by default)
* pic
* strictoverflow
* format
* relro
* bindnow

I've added an alias for multipath_tools to make sure that we don't break
existing configurations referencing the old name.

This seems to have been confusing people, using both xlibs and xorg, etc.
- Avoided renaming local (and different) xlibs binding in gcc*.
- Fixed cases where both xorg and xlibs were used.
Hopefully everything still works as before.
Xen required a few changes in order to be usable:
* Include xenfs module in initrd as loading it in the activation
script was failing.
* Include /etc/default/xendomains, which is needed by
xen-domains service.
* Create /var/log/xen and /var/lib/xen directories in
the xen-store service, which are needed by the xl command.
The directories could be created by any other script as long as
they are guaranteed to exist before xl is called.
* Fix a reference to /bin/ls in the xendomains script.
