clang on Fedora started to complain about some calls to g_new0()
we're making in vbox_snapshot_conf.c. Specifically, we're passing
zero as number of elements to allocate. And while usually SA
tools are not clever, in this specific case clang is right.
There are three cases where such call is made, but all of them
later use VIR_EXPAND_N() to allocate more memory (if needed). But
VIR_EXPAND_N() accepts a variable set to NULL happily.
Therefore, just drop those three calls to g_new0(..., 0) and let
VIR_EXPAND_N() allocate memory.

In QEMU and LXC drivers in a few places only
virNetDevBandwidthClear() is called. This means that if an
interface is of openvswitch vport profile, its QoS is not
removed. And to make matters worse - OVS is designed to remember
state even when corresponding interface is gone. This leads to
stale QoS settings piling up in OVS database.
To resolve this, introduce virDomainInterfaceClearQoS() which
looks at given interface and calls corresponding QoS clear
function. Then, basically replace virNetDevBandwidthClear() calls
in those hypervisor drivers with this new function.

The reason virDomainClearNetBandwidth() exists in src/conf/ is
that at the time its introduction we did not have a better place.
But now we do. Firstly, virDomainClearNetBandwidth() is
hypervisor agnostic code, but really has nothing to do with
domain configuration (it doesn't parse/format XML). Secondly, in
near future it'll call another function from src/hypervisor/ and
that's not really allowed from src/conf/.

When performing an install, it's common for tooling such as virt-install
to remove the install kernel/initrd once they are successfully booted and
the domain has been redefined to boot without them. After the installation
is complete and the domain is rebooted/shutdown, the DAC and selinux
security drivers attempt to restore labels on the now deleted files. It's
harmles wrt functionality, but results in error messages such as
Mar 08 12:40:37 virtqemud[5639]: internal error: child reported (status=125): unable to stat: /var/lib/libvirt/boot/vir>
Mar 08 12:40:37 virtqemud[5639]: unable to stat: /var/lib/libvirt/boot/virtinst-yvp19moo-linux: No such file or directo>
Mar 08 12:40:37 virtqemud[5639]: Unable to run security manager transaction
Add a check for file existence to the virSecurity*RestoreFileLabel functions,
and avoid relabeling if the file is no longer available. Skipping the restore
caused failures in qemusecuritytest, which mocks stat, chown, etc as part of
ensuring the security drivers properly restore labels. virFileExists is now
mocked in qemusecuritymock.c to return true when passed a file previously
seen by the mocked stat, chown, etc functions.

At the moment, there is no configuration option for the libvirt-guests
service that allows users to define that only persistent virtual machines
should be shutdown on host shutdown.
Currently, the service config allows to choose between two ON_SHUTDOWN
actions that are executed on running virtual machines when the host goes
down: shutdown, suspend.
The ON_SHUTDOWN action should be orthogonal to the type of the virtual
machine. However, the existing implementation, does not suspend
transient virtual machines.
This is the matrix of actions that is executed on virtual machines based
on the configured ON_SHUTDOWN action and the type of a virtual machine.
| persistent | transient
shutdown | shutdown | shutdown (what we want to change)
suspend | suspend | nothing
Add config option PERSISTENT_ONLY to libvirt-guests config that allows
users to define if the ON_SHUTDOWN action should be applied only on
persistent virtual machines. PERSISTENT_ONLY can be set to true, false,
default. The default option will implement the already existing logic.
Case 1: PERSISTENT_ONLY=default
| persistent | transient
shutdown | shutdown | shutdown
suspend | suspend | nothing
Case 2: PERSISTENT_ONLY=true
| persistent | transient
shutdown | shutdown | nothing
suspend | suspend | nothing
Case 3: PERSISTENT_ONLY=false
| persistent | transient
shutdown | shutdown | shutdown
suspend | suspend | suspend
