When removing SSH keys via set-user-sshkeys virsh command, then
files to remove are read from passed file. But when
experimenting, I've passed /dev/null as the file which resulted
in API checks which caught that @keys argument of
virDomainAuthorizedSSHKeysSet() can't be NULL. This is because if
the file is empty then its content is an empty string and thus
the buffer the file was read in to is not NULL.
Long story short, error is reported correctly, but it's not
necessary to go through public API to catch it.

In v6.10.0-rc1~104 I've added a virsh command that exposes
virDomainAuthorizedSSHKeysSet() API under "set-user-sshkeys"
command. The command accepts mutually exclusive "--reset" and
"--remove" options (among others). While the former controls the
VIR_DOMAIN_AUTHORIZED_SSH_KEYS_SET_APPEND flag, the latter
controls the VIR_DOMAIN_AUTHORIZED_SSH_KEYS_SET_REMOVE flag.
These flags are also mutually exclusive. But the code that sets
them has a logical error which may result in both flags being
set. In fact, this results in user being not able to set just the
remove flag.

The comment that

Was correct at the time, but has since been addressed by
qemu/qemu@105fad6bb2, which added support for set-time without a time
argument, as used by `virsh domtime --sync` by libvirt-guests.sh. I can
confirm that `virsh domtime --sync` works correctly on a Windows 10
guest, as does `SYNC_TIME=1`. (Note that there can be a significant
delay between when the command completes and when the guest time
finishes synchronizing due to QEMU GA calling `w32tm` with `/nowait`,
which complicates testing.)

Using virtCgroupNewSelf() is not correct with cgroups v2 because the
the virt-host-validate process is executed from from the same cgroup
context as the terminal and usually not all controllers are enabled
by default.
To do a proper check we need to use the root cgroup to see what
controllers are actually available. Libvirt or systemd ensures that
all controllers are available for VMs as well.
This still doesn't solve the devices controller with cgroups v2 where
there is no controller as it was replaced by eBPF. Currently libvirt
tries to query eBPF programs which usually works only for root as
regular users will get permission denied for that operation.

This patch adds new schema and adds support for parsing and formatting

vDPA network devices allow high-performance networking in a virtual
machine by providing a wire-speed data path. These devices require a
vendor-specific host driver but the data path follows the virtio
specification.
When a device on the host is bound to an appropriate vendor-specific
driver, it will create a chardev on the host at e.g. /dev/vhost-vdpa-0.
That chardev path can then be used to define a new interface with
type='vdpa'.

WITH_VIRTUALPORT just checks that we are building on Linux and that
IFLA_PORT_MAX is defined in linux/if_link.h. Back when 802.11Qb[gh]
support was added, the IFLA_* stuff was new (introduced in kernel
2.6.35, backported to RHEL6 2.6.32 kernel at some point), and so this
extra check was necessary, because libvirt was being built on Linux
distros that didn't yet have IFLA_* (e.g. older RHEL6, all
RHEL5). It's been in the kernel for a *very* long time now, so all
supported versions of all Linux platforms libvirt builds on have it.
Note that the above paragraph implies that the conditional compilation
should be changed to #if defined(__linux__). However, the astute
reader will notice that the code in question is sending and receiving
netlink messages, so it really should be conditional on WITH_LIBNL
(which implies __linux__) instead, so that's what this patch does.
