This mostly just replaces upto 3 fields in the driver state
with a single new virInhibitor object, but otherwise should not
change functionality besides replacing atomics with mutex protected
APIs.
The exception is the LXC driver which has been trying to inhibit
shutdown shutdown but silently failing to, since nothing ever

The system inhibitor locks are currently handled by code in the
virNetDaemon class. The driver code invokes a callback provided
by the daemon when it wants to start or end inhibition.
When the first inhibition is started, the daemon will call out
to logind to apply it system wide.
This has many flaws
* A single message is registered with logind regardless of
what driver holds the inhibition
* An inhibition of daemon shutdown can't be acquired
without also inhibiting system shutdown
* Config of the inhibitions cannot be tailored by the
driver
The new virInhibitor object addresses these:
* The object directly manages an inhibition with logind
privately to the driver, enabling custom messages to
be set.
* It is possible to acquire an inhibition locally to the
daemon without forwarding it to logind.

IOW, on Linux we have long been able to assume that QEMU core
dumps will exclude guest memory, unless the user has overridden
the host level defaults in the domain XML.
It is desirable to permit QEMU core dumps out of the box to make
it easier for users to report crashes to their OS vendor without
having to reconfigure and restart libvirt daemons and their
running guests.
While there is a risk that an admin may have set 'dump_guest_core'

of easier troubleshooting outweigh the risk of changing the

The docs for submitting a patch describe using your "Legal Name" with
the Signed-off-by line.
In recent times, there's been a general push back[1] against the notion
that use of Signed-off-by in a project automatically requires / implies
the use of legal ("real") names and greater awareness of the downsides.
Full discussion of the problems of such policies is beyond the scope of
this commit message, but at a high level they are liable to marginalize,
disadvantage, and potentially result in harm, to contributors.
TL;DR: there are compelling reasons for a person to choose distinct
identities in different contexts & a decision to override that choice
should not be taken lightly.
A number of key projects have responded to the issues raised by making
it clear that a contributor is free to determine the identity used in
SoB lines:
* Linux has clarified[2] that they merely expect use of the
contributor's "known identity", removing the previous explicit
rejection of pseudonyms.
* CNCF has clarified[3] that the real name is simply the identity
the contributor chooses to use in the context of the community
and does not have to be a legal name, nor birth name, nor appear
on any government ID.
Since we have no intention of ever routinely checking any form of ID
documents for contributors[4], realistically we have no way of knowing
anything about the name they are using, except through chance, or
through the contributor volunteering the information. IOW, we almost
certainly already have people using pseudonyms for contributions.
This proposes to accept that reality and eliminate unnecessary friction,
by following Linux & the CNCF in merely asking that a contributors'
commonly known identity, of their choosing, be used with the SoB line.

There are two scenarios identified after the recent firewall backend
selection was introduced, which result in libvirtd failing to startup
due to an inability to find either iptables/nftables
- On Linux if running unprivileged with $PATH lacking the dir
containing iptables/nftables
- On non-Linux where iptables/nftables never existed
In the former case, it is preferrable to restore the behaviour whereby
the driver starts successfully. Users will get an error reported when
attempting to start any virtual network, due to the lack of permissions
needed to create bridge devices. This makes the missing firewall backend
irrelevant.
In the latter case, the network driver calls the 'nop' platform
implementation which does not attempt to implement any firewall logic,
just allowing the network to start without firewall rules.
To solve this are number of changes are required
* Introduce VIR_FIREWALL_BACKEND_NONE, which does nothing except
report a fatal error from virFirewallApply(). This code path
is unreachable, since we'll never create a virFirewall
object with with VIR_FIREWALL_BACKEND_NONE, so the error reporting
is just a sanity check.
* Ignore the compile time backend defaults and assume use of
the 'none' backend if running unprivileged.
This fixes the first regression, avoiding the failure to start
libvirtd on Linux in unprivileged context, instead allowing use
of the driver and expecting a permission denied when creating a
bridge.
* Reject the use of compile time backend defaults no non-Linux
and hardcode the 'none' backend. The non-Linux platforms have
no firewall implementation at all currently, so there's no
reason to permit the use of 'firewall_backend_priority'
meson option.
This fixes the second regression, avoiding the failure to start
libvirtd on non-Linux hosts due to non-existant Linux binaries.
* Change the Linux platform backend to raise an error if the
firewall backend is 'none'. Again this code path is unreachable
by default since we'll fail to create the bridge before getting
here, but if someone modified network.conf to request the 'none'
backend, this will stop further progress.
* Change the nop platform backend to raise an error if the
firewall backend is 'iptables' or 'nftables'. Again this code
path is unreachable, since we should already have failed to
find the iptables/nftables binaries on non-Linux hosts, so
this is just a sanity check.
* 'none' is not permited as a value in 'firewall_backend_priority'
meson option, since it is conceptually meaningless to ask for
that on Linux.
NB, 'firewall_backend_priority' allows repeated options temporarily,
which we don't want. Meson intends to turn this into a hard error
DEPRECATION: Duplicated values in array option is deprecated. This will become a hard error in the future.
and we can live with the reduced error checking until that happens.

The virt-pki-validate tool is currently a shell script. We have a

This new implementation the same output format as the host validation
tool for a more consistent user experiance.
It also eliminates the requirement to have certtool installed on
libvirt hosts, which has been an issue for Fedora flatpak packages
since certtool isn't in the default platform runtime.

The /etc/sysconfig/libvirtd file is a Fedora/RHEL specific concept.
Since those distros switched to systemd socket activation, the
existance of --listen parameter in /etc/sysconfig/libvirtd is no
longer a reliable check. This was further degraded with the switch
to modular daemons where virtproxyd takes over the role.
The /etc/sysconfig/iptables file is a Fedora/RHEL specific concept.
Since those distros switched to firewalld, this file is no longer
