Introduced by commit 0832c58, with the intention to link with
the stack protector library.
Another instance introduced by commit 4cbc15d which separated
commandhelper_LDADD from LDADDS.
Not needed because per commit 71b54636, automake should pass
all the CFLAGS to the linker.
All the pieces are now in place, so we can finally start
using isolation groups to achieve our initial goal, which is
separating hostdevs from emulated PCI devices while keeping
hostdevs that belong to the same host IOMMU group together.

When looking for slots suitable for a PCI device, libvirt
might need to add an extra PCI controller: for pSeries guests,
we want that extra controller to be a PHB (pci-root) rather
than a PCI bridge.

PCI bus has to be numbered sequentially, and no index can be
missing, so libvirt will fill in the blanks automatically for
the user.
Up until now, it has done so using either pci-bridge, for machine
types based on legacy PCI, or pcie-root-port, for machine types
based on PCI Express. Neither choice is good for pSeries guests,
where PHBs (pci-root) should be used instead.

These tests demonstrate that, while it's now possible for the
user to create PHB explicitly and manually assign devices to
them, libvirt still defaults to extending the guest PCI
topology using PCI bridges and making suboptimal device
placement choices.
The next few commits will improve on these behaviors and the
tests outputs will automatically be updated to reflect this.

Currently the scan of the /proc/mounts file used to find cgroup mount
points doesn't take into account that mount points may hidden by other
mount points. For, example in certain Kubernetes environments the
/proc/mounts contains the following lines:
cgroup /sys/fs/cgroup/net_prio,net_cls cgroup ...
tmpfs /sys/fs/cgroup tmpfs ...
cgroup /sys/fs/cgroup/net_cls,net_prio cgroup ...
In this particular environment the first mount point is hidden by the
second one. The correct mount point is the third one, but libvirt will
never process it because it only checks the first mount point for each
controller (net_cls in this case). So libvirt will try to use the first
mount point, which doesn't actually exist, and the complete detection
process will fail.
To avoid that issue this patch changes the virCgroupDetectMountsFromFile
function so that when there are duplicates it takes the information from
the last line in /proc/mounts. This requires removing the previous
explicit condition to skip duplicates, and adding code to free the
memory used by the processing of duplicated lines.

Use the full storage driver registration method that also fails if one
of the storage backends is not present. This makes the test fail if a
submodule fails registration, which is useful for testing.
Additionally return EXIT_FAILURE as usual in tests rather than -1.
On domain startup, bind host or bind service can be omitted
and we will format a working command line.
Extend this to hotplug as well and specify the service to QEMU
even if the host is missing.

Sheepdog and possibly others use nested objects for network server and
thus could be specified in a way that libvirt would not parse.
Validates that https://bugzilla.redhat.com/show_bug.cgi?id=1464821
is fixed properly.
If a value of the first level object contains more objects needing
deflattening which would be wrapped in an actual object the function
would not recurse into them.
By this simple addition we can fully deflatten the objects.
As it turns out sometimes users pass in an arbitrarily nested structure
e.g. for the qemu backing chains JSON pseudo protocol. This new
implementation deflattens now a single object fully even with nested
keys.
Additionally it's not necessary now to stick with the "file." prefix for
the properties.
Users may want to run the init command of a container as a special
user / group. This is achieved by adding <inituser> and <initgroup>
elements. Note that the user can either provide a name or an ID to
specify the user / group to be used.
This commit also fixes a side effect of being able to run the command
as a non-root user: the user needs rights on the tty to allow shell
job control.

Some qemu arch/machine types have built in platform devices that
are always implicitly available. For platform serial devices, the
current code assumes that only old style -serial config can be
used for these devices.
Apparently though since -chardev was introduced, we can use -chardev
in these cases, like this:
-chardev pty,id=foo
-serial chardev:foo
Since -chardev enables all sorts of modern features, use this method
for platform devices.

vcpu properties gathered from query-hotpluggable cpus need to be passed
back to qemu. As qemu did not use the node-id property until now and
libvirt forgot to pass it back properly (it was parsed but not passed
around) we did not honor this.
This patch adds node-id to the structures where it was missing and
passes it around as necessary.
The test data was generated with a VM with following config:
<numa>

Starting from qemu 2.9, more granular options are supported. Add parser
for the relevant bits.
With this patch libvirt is able to parse the host and target IQN of from
the JSON pseudo-protocol specification.
This corresponds to BlockdevOptionsIscsi in qemu qapi.
'SocketAddress' structure was changed to contain 'inet' instead of
'tcp' since qemu commit c5f1ae3ae7b. Existing entries have a backward
compatibility layer.
Libvirt will parse 'inet' and 'tcp' as equivalents.
