At two places we are open coding xdr_free():
remoteRelayDomainEventTunable() and
remoteRelayDomainEventJobCompleted().
Bot of these functions use make_nonnull_domain() to put domain
IDs tuple into return structure and then continue encoding the
rest of structure. If that fails, they call VIR_FREE() directly.
While this okay, we should use xdr_free() which frees the whole
return structure for us.

The return structure is a bit complicated and that's why it is
very easy to check for RPC limits incorrectly. The structure is
an array of remote_domain_stats_record structures with the limit
of REMOTE_DOMAIN_LIST_MAX. The latter structure then poses a
different limit on typed params:
REMOTE_CONNECT_GET_ALL_DOMAIN_STATS_MAX (which is what we are
checking for mistakenly).

If a libvirt error occurred during a test, then virTestRun()
reports it (regardless of test returning success or failure).
For instance, in this specific case, a hostdev is detached twice
and the second attempt is expected to fail. It does fail and
libvirt error is reported which is then printed onto stderr.

that.

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.

All code using LOCALSTATEDIR "/run" is updated to use RUNSTATEDIR
instead. The exception is the remote driver client which still
uses LOCALSTATEDIR "/run". The client needs to connect to remote
machines which may not be using /run, so /var/run is more portable
due to the /var/run -> /run symlink.
