This commit includes a test case for multiple network definitions. It is
useful right now, but it will be more useful when the index used by LXC
version 3.X is implemented to support this new settings. The version 3.X
is using indexes to specify each network settings.

This commit fixes a bug when you have multiple network settings defined.
Basically, if you set an IPv6 or IPv4 gateway, it carries on next
network settings. It is happening because the data is not being
initialized when a new network type is defined. So, the old data still
persists into the pointer. Another way to initialized the data was
introduced using memset() to avoid missing attributes from the struct.

The virt-pki-validate tool is extracting components in the x509
certificate Subject field. Unfortunately the regex it is is using is far
too strict, and so truncating valid data. It needs to consider ',' as a
field separator, and if that's not there take all data until the EOL.
With the broken regex:
$ echo " Subject: O=Test,CN=guestHyp1ver" | sed 's+.*CN=\(.[a-zA-Z \._-]*\).*+\1+'
guestHyp
And with the fixed regex
$ echo "Subject: O=Test,CN=guestHyp1ver" | sed 's+.*CN=\([^,]*\).*+\1+'

Commit 255e0732 introduced a few graphics-related helpers. The problem
is that virDomainGraphicsNeedsAutoRenderNode returns true if it gets
NULL as a response from virDomainGraphicsNeedsAutoRenderNode. That's
okay for egl-headless because that one always needs a DRM render node,
the same is not true for SPICE though, and unless the XML specifies
<gl enable='yes'> for SPICE, there's no need for any renderer.

Disable external snapshot of a readonly disk for domains as

If domain is killed with `xl destroy`, libvirt will not notice it and
still report the domain as running. Also trying to destroy the domain
through libvirt will fail. The only way to recover from such a situation
is to restart libvirt daemon. The problem is that even though libxl
report LIBXL_EVENT_TYPE_DOMAIN_DEATH, libvirt ignore it as all the
domain cleanup is done in a function actually destroying the domain. If
destroy is done outside of libvirt, there is no place where it would be
handled.
Fix this by doing domain cleanup in LIBXL_EVENT_TYPE_DOMAIN_DEATH too.
To avoid doing it twice, add a ignoreDeathEvent flag
libxlDomainObjPrivate, set when the domain death is triggered by libvirt
itself.

Commit 017dfa27d changed a few switch statements in the LXC code to
have all possible enum values, and in the process changed the switch
statement in virLXCControllerGetNICIndexes() to return an error status
for unsupported interface types, but it erroneously put type='direct'
on the list of unsupported types.
type='direct' (implemented with a macvlan interface) is supported on
LXC, but it's interface shouldn't be placed on the list of interfaces
given to CreateMachineWithNetwork() because the interface is put
inside the container, while CreateMachineWithNetwork() only wants to
know about the parent veths of veth pairs (the parent veth remains on
the host side, while the child veth is put into the container).

virLXCControllerGetNICIndexes() was deciding whether or not to add the
ifindex for an interface's ifname to the list of ifindexes sent to
CreateMachineWithNetwork based on the interface type stored in the
config. This would be incorrect in the case of <interface
type='network'> where the network was giving out macvlan interfaces
tied to a physical device (i.e. when the actual interface type was
"direct").
Instead of checking the setting of "net->type", we should be checking
the setting of virDomainNetGetActualType(net).
I don't think this caused any actual misbehavior, it was just
technically wrong.

The networkxml2firewalltest sets virCommand to dry run mode but doesn't
provide a callback to fill in stdout/stderr. As a result when the
firewall code queries rules it gets a NULL output and so never triggers
the callback to process output.
This trivial change just returns an empty string for the command output
in order to ensure the callback gets triggered. It has no effect right
now, but in future patches this will trigger greater test coverage.

Commit 212dc9286 made a generic qemuDomainGetIOThreadsMon which
would fail if the QEMU_CAPS_OBJECT_IOTHREAD didn't exist. Then
commit d1eac927 used that helper for the collection of all domain
stats. However, if the capability doesn't exist, then the entire
stats collection fails. Since the IOThread stats were meant to be
if available only, thus rather than failing if the capability
doesn't exist, let's just not collect the stats. Restore the caps

During qemuConnectGetAllDomainStats if qemuDomainGetStats causes
a failure, then when collecting more than one domain's worth of

collection failed.

"error: An error occurred, but the cause is unknown".
