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.

We already use templating to generate sockets, which are all
based off libvirtd's. Push the idea further, and extend it to
cover services as well.
This is more challenging, as the various modular daemons each have
their own needs in terms of what system services needs to be
available before they can be started, which other components of
libvirt they depend on, and so on.
In order to make this sort of per-service tweaks possible, we
introduce a Python script that can merge two systemd units
together. The script is aware of the semantics of systemd's unit
definition format, so it can intelligently merge sections
together.
This generic systemd unit merging mechanism will also supersede
the extremely ad-hoc @deps@ variable, which is currently used in
a single scenario.

Since all messages marked for translation contain permutable format
strings, we can add checks for enforcing them.
The syntax check does not catch all cases as it only checks format
strings between _(" and the first ". In other words messages where \"
appears before the first format string or multi-line messages where the
first format strings is not in the first line will not be checked. On
the other hand, it's run automatically by "meson test".
check-pot.py python script will detect all incorrect format strings, but
it's not as easy to use as it requires libvirt.pot to be regenerated and
this does not happen during a standard build. The following steps are
needed to check messages with check-pot.py:
meson compile libvirt-pot-dep
meson compile libvirt-pot
meson compile libvirt-pot-check
Don't forget to revert changes to libvirt.pot if you run these commands
locally as we don't want each patch series to update libvirt.pot.
Shell scripts (tools/libvirt-guests.sh.in is the only one currently)
need to be exempt from this check as shell's printf function does not
understand the permutable format strings.

But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to

virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

This script works under two specific conditions. For each opened file,
search for all functions that has ACL calls and store them, and see
if there is a vir*DriverPtr struct declared in it. For each implementation
found, check if there is an ACL verification inside it, and error out if
none was found. The script also supports the concept of stub, where another
function takes the responsibility for the ACL call instead of the
original API.
Unfortunately this is not enough to cover the new scenario we have now,
with domain_driver.c containing helper functions that execute the ACL
calls. The script does not store state between files because, until now,
it wasn't needed to - APIs and stubs and vir*DriverPtr declarations were
always in the same file. Also, the script will not check for ACL in functions
that does not belong to a vir*DriverPtr interface. What we have now in
domain_driver.c breaks both assumptions: the functions are in a different
file, and there is no vir*DriverPtr being implemented in the file that
uses these functions.
This patch changes check-aclrules.py to accomodate this scenario. The helpers
that have ACL checks are stored beforehand in aclFuncHelpers, allowing other
files to use them to recognize a stub situation. In case the current file
being analyzed is domain_driver.c itself, we'll do a manual check using
aclFuncHelpers to verify that these functions indeed have ACL checks.
