4cf223962a qemuDomainDiskCachemodeFlags: Simplify usage
Return whether a relevant cachemode was presented rather than returning
an error, so that callers can be simplified. Use the proper enum type as
argument rather than typecasting in the switch statement.

95e6615cd2 systemd: Set service_extra_in/socket_extra_in everywhere
It's somewhat confusing that some of the services have a
corresponding foo.service.extra.in and foo.socket.extra.in, some
have just one of the two, and some have neither.

In order to make things more approachable, make sure that both
files exists for each service.

In most cases the extra units are currently unused, so they will
just contain a comment briefly explaining their purpose and
pointing users to meson.build, where they can find more
information. The same comment is also added to the top of
extra units that already have some contents in them for
consistency.

b1aeca5db0 systemd: Support merging multiple units
In order to further deduplicate the contents of the various unit
files, we need to be able to merge multiple additional units
into the initial one.

Luckily the merge logic is in no way constrained to working with
just two units, so achieving this is pretty much just a matter
of lifting the existing limitation on the number of arguments
that the script accepts.

As a special case, it's now also possible to call the script
with just the base unit as argument. No merging will be performed
in that case, obviously, but we'll still go through the basic
validation and cleanup steps.

This also fixes a bug in the check for the number of arguments:
sys.argv also contains the name of the script, so we should have
checked that its size was at least 3. The check is now written in
a way that's less prone to misunderstandings.

1622012cc4 specfile: use correct option for nbdkit in mingw build
commit v9.8.0-40-g7cbd8c4230 changed the name of the option that
enables/disables nbdkit support in the build from "libnbd" to
"nbdkit", but one use of "libnbd=disabled" was missed in
libvirt.specfile.in - the meson commandline for mingw.

This patch changes that line to "-Dnbdkit=disabled", thus unbreaking
the rpm build.
