The code registering the event handlers in 'cmdEvent' had too many
blocks of code conditional on whether just one event is being listened
to or all events.
The code can be greatly simplified by uniting the code paths and having
only one branch when filling the list of events we want to listen for.

'cmdEvent' along with all the helper functions it needs is ~950 LOC.
Move it out from virsh-domain.c to virsh-domain-event.c along with the

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.

Adding an exception for the whole file usually defeats the purpose of a
syntax check and is also likely to get forgotten once the file is
removed.
In case of the suggestion of using 'safewrite' instead of write even the
comment for safewrite states that the function needs to be used only in
certain cases.
Remove the blanket exceptions for files and use an exclude string
instead. The only instance where we keep the full file exception is for
src/libvirt-stream.c as there are multiple uses in example code in
comments where I couldn't find a nicer targetted wapproach.

They way our VIR_ENUM_IMPL() and virXXXTypeFromString() work is
that for any string that's not recognized a negative one is
returned. And, since VIR_XXX_LAST is passed to VIR_ENUM_IMPL() we
can be sure that all enum members are covered. Therefore, there
is no way that virXXXTypeFromString() can return a value that's
bigger or equal to VIR_XXX_LAST.
I've noticed two places where such comparison was made, both in
cmdNetworkUpdate(). Drop them.

liberty to put anything they want into these files. This makes it

shared_module() is intended for shared objects that are
loaded at runtime using dlopen() whereas NSS plugins need to
be full-fledged shared libraries with, among other things, a
proper SONAME.
Meson seems to have become more strict about this recently,
because libnss_libvirt.so.2 gets a SONAME when I build it with
Meson 0.59.4 on Fedora 34 but doesn't when I use Meson 0.60.2
on Debian testing instead.
Either way, shared_library() was always the right function
to use for NSS plugins.
