Although virDomainDeviceDefValidate() is called as a part of
parsing device XML routine, it validates only that single device.
The virDomainDefValidate() function performs a more comprehensive
check. It should detect errors resulting from dependencies
between devices, or a device and some other part of XML config.
Therefore, a call to virDomainDefValidate() is added at the end
of qemuDomainAttachDeviceConfig().

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.
