When building the default memory backend (which has id='pc.ram')
and no guest NUMA is configured then
qemuBuildMemCommandLineMemoryDefaultBackend() is called. However,
its return value is ignored which means that on invalid
configuration (e.g. when non-existent hugepage size was
requested) an error is reported into the logs but QEMU is started
anyway. And while QEMU does error out its error message doesn't
give much clue what's going on:
qemu-system-x86_64: Memory backend 'pc.ram' not found
While at it, introduce a test case. While I could chose a nice
looking value (e.g. 4MiB) that's exactly what I wanted to avoid,
because while such value might not be possible on x84_64 it may
be possible on other arches (e.g. ppc is notoriously known for
supporting wide range of HP sizes). Let's stick with obviously
wrong value of 5MiB.

Before creating a NVRAM path, the qemuDomainNVRAMPathGenerate
method checks whether the config is using the old style
firmware approach. This check is redundant in one of the two
callers. By inlining the check into the other caller, it makes
it clearer to understand that the NVRAM path filling is done
conditionally.

Since libvirt-guests script/service can operate on various URIs and we do
support both socket activation and traditional services, the ordering should be
specified for all the possible sockets and services.
Also remove the Wants= dependency since do not want to start any service. We
cannot know which one libvirt-guests is configured, so we'd have to start all
the daemons which would break if unused colliding services are not
masked (libvirtd.service in the modular case and all the modular daemon service
units in the monolithic scenario). Fortunately we can assume that the system is
configured properly to start services/sockets that are of interest to the user.
That also works with the setup described in https://libvirt.org/daemons.html .
To make it even more robust we add the daemon service into the machine units
created for individual domains as it was missing there.

Our last default template had a match of "node()" which incidentally matched
everything, including text nodes. Since this has the same priority according to
the XSLT spec, section 5.5:
https://www.w3.org/TR/1999/REC-xslt-19991116#conflict
this is an error. Also according to the same spec section, the XSLT processor
may signal the error or pick the last rule.
This was uncovered with libxslt 1.1.35 which contains the following commit:
b0074eeca3
which makes the build fail with:
runtime error: file ../docs/page.xsl line 223 element element
xsl:element: The effective name '' is not a valid QName.
because our last rule also matches text nodes and we are trying to extract the
node name out of them.
To fix this we change the match to "*" which only matches elements and not all
the nodes, and to avoid any possible errors with different XSLT processors we
also bump the priority of the match="text()" rule a little higher, just in case
someone needs to use an XSLT processor that chooses signalling the error instead
of the optional recovery.
