A completer must return a NULL terminated list of strings, which
means that when dealing with enums, it has to allocate one
pointer more than the value of VIR_XXX_LAST. But this is not
honoured in virshDomainInterfaceSourceModeCompleter() leading to
out of bounds read.

When using thue 'run' script to launch a daemon, it is intended to
temporarily stop the systemd units and re-start them again after.
When using this script over an SSH connection, it will get SIGHUP
if the connection goes away, and in this case it fails to re-start
the systemd units. We need to catch SIGHUP and turn it into a
normal python exception. For good measure we do the same for
SIGQUIT and SIGTERM too. SIGINT already gets turned into an
exception by default which we handle.

Long ago we adapted to Linux kernel changes which inverted the
behaviour of the conntrack --ctdir setting:
commit a6a04ea47a
Author: Stefan Berger <stefanb@us.ibm.com>
Date: Wed May 15 21:02:11 2013 -0400
nwfilter: check for inverted ctdir
Linux netfilter at some point (Linux 2.6.39) inverted the meaning of the
'--ctdir reply' and newer netfilter implementations now expect
'--ctdir original' instead and vice-versa.
We check for the kernel version and assume that all Linux kernels with version
2.6.39 have the newer inverted logic.
Any distro backporting the Linux kernel patch that inverts the --ctdir logic
(Linux commit 96120d86f) must also backport this patch for Linux and
adapt the kernel version being tested for.
Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>
Given our supported platform targets, we no longer need to
consider a version of Linux before 2.6.39, so can drop
support for the old direction behaviour.
The test suite updates are triggered because that never
probed for the ctdir direction, and so the iptables syntax
generator unconditionally dropped the ctdir args.

Since iptables version 1.4.16 '-m state --state NEW' is converted to

versions of iptables use '-m conntrack --ctstate'.
Given our supported platform targets, we no longer need to
