In most cases the replacement is straightforward, with the
biggest difference being that we now schedule restarts during
%pre instead of %post. This also means that we can get rid of
%post for most packages, reducing the number of scriptlets that
need to run during install/upgrade.
Notable exceptions are libvirt-guests.service, where we stop
using the standard systemd macros to adopt our custom ones, as
well as the virtlogd and virtlockd services, where the reload
operation is moved from %postun to %posttrans.

systemd provides a number of standard RPM macros but they don't
quite satisfy our requirements, as evidenced by the fact that we
have already built some custom tooling around them.
Scenarios that the standard macros don't cover and that we're
already addressing with our custom ones:
* for some services (libvirtd, virtnetworkd, virtnwfilterd)
there are multiple conditions that might lead to a restart,
and we want to make sure that they're not needlessly
restarted several times per transaction;
* some services (virtlogd, virtlockd) must not be restarted
during upgrade, so we have to reload them instead.
Issues that neither the standard macros nor our custom ones
address:
* presets for units should be applied when the unit is first
installed, not when the package that contains it is.
The package split that happened in 9.1.0 highlighted why this
last point is so important: when virtproxyd and its sockets
were moved from libvirt-daemon to the new libvirt-daemon-proxy
package, upgrades from 9.0.0 caused presets for them to be
applied.
On a platform such as Fedora, where modular daemons are the
default, this has resulted in breaking existing deployments in
at least two scenarios.
The first one is machines that were configured to use the
monolithic daemon, either because the local admin had manually
changed the configuration or because the installation dated
back to before modular daemons had become the default. In this
case, virtproxyd.socket being enabled resulted in a silent
conflict with libvirtd.socket, which by design shares the same
path, and thus a completely broken setup.
The second one is machines where virtproxy-tls.socket, which is
disabled by default, had manually been enabled: in this case,
applying the presets resulted in it being disabled and thus a
loss of remote availability.
Note that these are just two concrete scenarios, but the problem
is more generic. For example, if we were to add more units to an
existing package, per the current approach they wouldn't have
their presets applied.
The new macros are designed to avoid all of the pitfalls
mentioned above. As a bonus, they're also simpler to use: where
the current approach requires restarts and other operations to
be handled separately, the new one integrates the two so that,
for each scriptlet, a single macro call is needed.

This logic was necessary when socket activation was introduced
in libvirt 5.6.0/5.7.0 in order to guarantee smooth upgrades.
These days, even the oldest platform that we target ships a
version of libvirtd that implements socket activation, so the
additional code is no longer useful and we can treat libvirtd
the same as all other services.

The current implementation pretty much assumes that targets
where modular daemons are the default will stick with that
configuration, as will targets where they're not, or that
changes to these defaults will be performed by the admin after
the packages have been installed.
This is unnecessarily limiting: for example, on a target that
defaults to using the monolithic daemon, it's entirely possible
to create a local preset such as
# /etc/systemd/system-preset/00-virt.preset
disable libvirtd.service
disable libvirtd*.socket
enable virtqemud.service
to opt into a modular daemon deployment. The opposite is of
course also true. We shouldn't get in the way of these
reasonable use cases.

The virRandomGenerateWWN() is used solely by nodedev driver to
autogenerate WWNN and WWNP when parsing a nodedev XML. Now, the
idea was (at least during monolithic daemon) that depending on
which hypervisor driver called the nodedev XML parsing (and
virRandomGenerateWWN() under the hood) the corresponding OUI is
used (e.g. "001a4a" for the QEMU driver).
But in era of split daemons things are not that easy. We do not
know which hypervisor driver called us. And there might be no
hypervisor driver at all - users are allowed to connect to
individual drivers directly (e.g. "nodedev:///system").
In this case, we can't use proper OUI. Well, do the next best
thing: pick one (QUMRANET_OUI).

When automatically adding a NUMA node (qemuDomainDefNumaAutoAdd()) the
memory size of the node is computed as:
total_memory - sum(memory devices)
And we have a nice helper for that: virDomainDefGetMemoryInitial() so
it looks logical to just call it. Except, this code runs in post parse
callback, i.e. memory sizes were not validated and it may happen that
the sum is greater than the total memory. This would be caught by
virDomainDefPostParseMemory() but that runs only after driver specific
callbacks (i.e. after qemuDomainDefNumaAutoAdd()) and because the
domain config was changed and memory was increased to this huge
number no error is caught.
So let's do what virDomainDefGetMemoryInitial() would do, but
with error checking.
