Use the latest virt-manager to regenerate the files.

The command line is once again along the lines of

  $ virt-install \
    --name guest --os-variant fedora29 \
    --vcpus 4 --memory 4096 --disk size=5 \
    --graphics (none|vnc) \
    --print-xml

with some minor tweaks performed afterwards.

This removes a number of inconsistencies between the files,
and makes it so the only differences are actually relevant
either to the architecture and machine type at hand, or to
having graphics rather than being headless.

Right now *-headless and *-graphics tests are using different
quoting styles, which results in the diff between them being
basically useless, whereas we would like it to be possible to
compare these files directly and easily spot the differences.

Convert all *-graphics tests to single quotes, which is the
style libvirt itself uses when formatting XML: this is a fact
that will come in handy later.

Commit a7fb2258 added sanitization of storage pool target paths,
however source dir paths were left unsanitized.

A netfs pool with:
<source>
  <host name='10.20.30.40'/>
  <dir path='/nfs/'/>
</source>
will not be correctly detected as mounted by
virStorageBackendFileSystemIsMounted, because it shows up in the
mount list without the trailing slash.

Sanitize the source dir as well.

Similarly how we allow adding arbitrary command line arguments and
environment variables this patch introduces the ability to control
libvirt's perception of the qemu process by tweaking the capability bits
for testing purposes.

The idea is to allow developers and users either test a new feature by
enabling it early or disabling it to see whether it introduced
regressions.

This feature is not meant for production use though, so users should
handle it with care.

Libvirtd has long had integration with avahi for advertising libvirtd
using mDNS when TCP/TLS listening is enabled. For a long time the
virt-manager application had support for auto-detecting libvirtds
on the local network using mDNS, but this was removed last year

  commit fc8f8d5d7e3ba80a0771df19cf20e84a05ed2422

    connect: Drop avahi support

    Libvirtd can advertise itself over avahi. The feature is disabled by
    default though and in practice I hear of no one actually using it
    and frankly I don't think it's all that useful

    The 'Open Connection' wizard has a disproportionate amount of code
    devoted to this feature, but I don't think it's useful or worth
    maintaining, so let's drop it

I've never heard of any other applications having support for using
mDNS to detect libvirtd instances. Though it is theoretically possible
something exists out there, it is clearly going to be a niche use case
in the virt ecosystem as a whole.

By removing avahi integration we can cut down the dependency chain for
the basic libvirtd install and reduce our code maint burden.

Allow using seclabels the same way as disk images allow it. Currently
the snapshot code copies the seclabels from the original image if no
seclabel is provided. Also there's no code change required as the
snapshot XML parser actually uses parts of the disk parser thus
seclabels are already parsed and formatted and even applied thus this is
just a formalization of our support for this.

With QEMU versions which lack "unavailable-features" we use CPUID based
detection of features which were enabled or disabled once QEMU starts.
Thus using MSR features with host-model would result in all of them
being marked as disabled in the active domain definition even though
QEMU did not actually disable them.

Let's make sure we add MSR features to host-model only when
"unavailable-features" property is supported by QEMU.
