Currently during RPM upgrade we restart libvirtd and unconditionally
enable use of systemd socket activation for the UNIX sockets.
If the user had previously given the --listen arg to libvirtd though,
this will no longer be honoured if socket activation is used.
We could start libvirtd-tcp.socket or libvirtd-tls.socket for this,
but mgmt tools like puppet/ansible might not be expecting this.
So for now we silently disable socket activation if we see --listen
was previously set on the host.

When using systemd socket activation the --listen arg has no
effect. This is confusing to users upgrading from previous versions of
libvirt as their config is silently ignored. Turn use of --listen into a
fatal error when sockets are passed from systemd.
This helps the admin discover the change in behaviour and thus decide
whether to stick with socket activation or revert to previous behaviour.

Many distros have moved /var/run to /run with the introduction of
systemd. /var/run still exists as a symlink to /run, but its usage
is deprecated.
autoconf added a --runstatedir option back in 2013 but there's still no
new release of autoconf that includes this.
gnulib meanwhile added support to propagate this arg's value to
configmake.h, but it falls back to $localstatedir/run for autoconf 2.69
and older, which is what every distro today has.
To deal with this problem we add a --with-runstatedir arg that then sets
the $runstatedir env variable that future autoconf's --runstatedir arg
will also use. This finally enables $runstatedir to be pointed to /run.

Since version 3.0, qemu has returned disk usage statistics in
guest-get-fsinfo. And since 3.1, it has returned information about the
disk serial number and device node of disks that are targeted by the
filesystem.
Unfortunately, the public API virDomainGetFSInfo() returns the
filesystem info using a virDomainFSInfo struct, and due to API/ABI
guarantees it cannot be extended. So this new information cannot
easily be added to the public API. However, it is possible to add this
new filesystem information to a new virDomainGetGuestInfo() API which
will be based on typed parameters and is thus more extensible.
In order to support these two use cases, I added an internal struct
which the agent code uses to return all of the new data fields. This
internal struct can be converted to the public struct at a cost of some
extra memory allocation.
In a following commit, this additional information will be used within
virDomainGetGuestInfo().

With the changes to the backing store string parsers we can report and
propagate if such a thing is present in the configuration and thus start
skipping those files in the backing chain traversal code. This approach
still allows to report the appropriate backing store string in the
