Instead of creating an empty object and then setting keys one
at a time, it is possible to pass a dict object to
configuration_data(). This is nicer because it doesn't require
repeating the name of the cfg_data object over and over.
There is one exception: the 'conf' object, where we store values
that are used directly by C code. In that case, using a dict
object is not feasible for two reasons: first of all, replacing
the set_quoted() calls would result in awkward code with a lot
of calls to format(); moreover, since code that modifies it is
sprinkled all over the place, refactoring it would probably
make things more complicated rather than simpler.

I've came across an aarch64 system which supports hugepages up to
16GiB of size. However, I was unable to allocate them using
virsh allocpages. This is because cmdAllocpages() uses
vshCommandOptScaledInt(), which scales passed value into bytes,
but since the virNodeAllocPages() expects size in KiB the
variable holding bytes is then divided by 1024. However, the
limit for the biggest value passed to vshCommandOptScaledInt() is
UINT_MAX which is now obviously wrong, as it needs to be UINT_MAX
* 1024.
The same bug is in completer. But here, let's use ULLONG_MAX so
that we don't have to care about it anymore.

Now that we have a function that generates string list for given
enum, let's use that instead of open coding it.
Note, after this there are still some 'candidates' left (e.g,
virshNetworkEventNameCompleter(), or
virshNetworkUpdateCommandCompleter()). These are not converted
because either they don't have a convenient int2str function or
they don't start from the very beginning of the enum.

We have plenty of completers which iterate over all values of

A completer must return a NULL terminated list of strings, which
means that when dealing with enums, it has to allocate one

honoured in virshDomainInterfaceSourceModeCompleter() leading to

We are not guaranteed that the string we are printing onto stdout
contains '\n' and thus that the stdout is flushed. In fact, I've
met this problem when virsh asked me whether I want to edit the
domain XML again (vshAskReedit()) but the prompt wasn't displayed
(as it does not contain a newline character) and virsh just sat
there waiting for my input, I sat there waiting for virsh's

Historically the use of the '-desc' multiple argument parameter was not
forbidden toghether with '-edit', but use of both together has some
unexpected behaviour. Specifically the editor is filled with the
contents passed via '-desc' but if the user doesn't change the text in
any way virsh will claim that the description was not chaged even if it
differs from the currently set description. Similarly, when the user
would edit the description provided via 'desc' so that it's identical
with the one configured for the domain, virsh would claim that it was
updated:
# virsh desc cd
No description for domain: cd
# EDITOR=true virsh desc cd --edit "test desc"
Domain description not changed
After the fix:
# virsh desc cd
No description for domain: cd
# EDITOR=true virsh desc cd --edit "test desc"
Domain description updated successfully
# EDITOR=true virsh desc cd --edit "test desc"
Domain description not changed

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.

Remove the blanket exceptions for files and use an exclude string
