The qemuAgent has option to issue guest-sync command before each
intended command or issue the sync commend just once, right after
the socket is opened and before the first intended command is
issued. The latter is referred to as single sync agent and is
enabled by VSERPORT_CHANGED event which allows us to detect
when the agent (dis-)connects in the guest.
Now, every QEMU that we support (4.2.0 or newer) has the event
and thus will use single sync agent. Therefore, adjust
qemuagenttest to make it test what's used in the real world,
rather than old approach.

The was an attempt to document the retvals for
qemuDomainQueryWakeupSuspendSupport(). However, it's misleading
because in reality, the function can return nothing but 0 or -1,
but the comment implies retval of 1 too.
Since the set of possible return values complies with our
unwritten rule (0 for success, -1 for error), there's no real
value in having the comment and as such can be dropped.

The libvirt-daemon subpackage contains libvirt-guests.sh script (used by
libvirt-guests service), which requires virsh to actually work. But
since dynamic libraries were separated from libvirt-client to
libvirt-libs more than 6 years ago, libvirt-daemon no longer requires
virsh to be installed. So unless libvirt-client is explicitly installed
(either manually or by installing the libvirt meta package),
libvirt-guests will not work.
Just adding libvirt-client as a dependency of libvirt-daemon would go
against the original idea behind splitting libvirt-client: users may not
want to install or use any client binaries on the host where the daemon
runs (either they just use various language bindings or access the
daemon remotely). To solve this we could possibly turn libvirt-daemon
into an empty package and separate the daemons and libvirt-guests into
subpackages to make sure we support both use cases, but marking
libvirt-client as Recommended for libvirt-daemon does the same job in a
much simpler way.

Historically, we had no idea whether the qemu-ga running inside
the guest was running or not. Or whether it crashed in the middle
of reading of a command. That's why we issued guest-sync prior
any intended command, to make the agent flush any partially read
JSON and reset its state machine.
But with VSERPORT_CHANGE event we know when the guest agent
(dis-)connects and thus can issue the sync command just once for
each 'connection'. Whether the agent is synced is tracked in
agent->inSync member, which used to be set to true upon
successful sync. But after rework in v8.0.0-rc1~361 that line is
gone, leaving us with using the historic approach basically.

Prior to firewalld version 1.0.0, the default action of ACCEPT in the
"libvirt" zone (subsequently overridden with a lower priority "REJECT"
action) would result in an implicit rule that allowed incoming sessions
through the zone; libvirt relied on this implicit rule to permit
incoming connections to guests that were connected via a libvirt
"routed" network.
Starting in firewalld 1.0.0, the rules generated for this same
zonefile changed such that incoming sessions through the libvirt zone
were no longer allowed, breaking the longstanding convention that they
should be allowed (only for routed networks).
However, beginning with firewalld 0.9.0, a zone can explicitly
allow/block forwarded traffic (by adding a "policy" to the zone that
specifies what happens to packets that are going in one zone and out
another zone).
This patch changes the zone for routed networks from "libvirt" to the
newly-added "libvirt-routed" zone that uses the new policy
functionality to once again allow incoming sessions to guests on
routed networks.
(If firewalld is < 0.9.0, then the policy file won't be read at all,
so firewalld won't log any error, and libvirt will just use the old
setup that takes advantage of the implicit forwarding rules).

Schema for <cpu> is taken from our main RNG schema, <cpuTest> is just a
