Later patches will implement support for <transient/> disks in libvirt
by installing an overlay on top of the configured image. This will
require cleanup after the VM will be stopped so that the state is
correctly discarded.
Since the overlay will be installed only during the startup phase of the
VM we need to ensure that qemuProcessStop doesn't delete the original
file on some previous failure. This is solved by adding
'inhibitDiskTransientDelete' VM private data member which is set prior
to any startup step and will be cleared once transient disk overlays are
established.
Based on that we can then delete the overlays for any <transient/> disk.

Commit f253dc90f5 introduced a test regression in environments with
Xen < 4.10. The logic in libxl_conf.c correctly maps ACPI and APIC
from virDomainObj to libxl_domain_conf based on
LIBXL_HAVE_BUILDINFO_APIC, but the tests did not account for the
different libxl_domain_conf JSON representations.
One approach to fixing the test regression is to duplicate JSON test
data files, having one set for Xen <= 4.9 and another for Xen 4.10
and greater. To avoid duplicate data files, this patch takes the
approach of modifying the libxl_domain_conf object based on
LIBXL_HAVE_BUILDINFO_APIC, before retrieving the JSON representation.
It allows using the same test data files for all supported versions
of Xen by adjusting the intermediate form of libxl_domain_conf object
as needed.

Add a container struct which holds all data needed to create and clean

'qemuSnapshotDiskDataPtr' the 'actions' of a transaction QMP command and
everything needed for cleanup at any given point.
This aggregation allows to simplify the arguments of the functions which
prepare the snapshot data and additionally will simplify the code
necessary for creating overlays on top of <transient/> disks.

When the xen driver loads, it probes libxl for some info about dom0 and
adds it to the virDomainObjList. The driver then looks for any domains
in stateDir and if they are still alive adds them to the list as well.
This logic is a bit flawed wrt handling driver reload and causes the
following error
internal error: unexpected domain Domain-0 already exists
A simple fix is to load all domains from stateDir first and then only
add dom0 if needed.

When an error is expected, the error message will be checked.
This is expressed by creating an additional ".err" file containing
the expected error message.
It is added in order to make sure the expected errors
are not masked by other errors during test execution while
leveraging the existing framework.
In order to keep it simple, an input file cannot be reused
anymore to cover several expected error cases configured
in the test code. An input file can still be reused by creating
a test case specific symlink.
For consistency, the mock needs to report an error now, too,
as every failure must have an error; otherwise a test case will
fail.
Require LC_ALL=C explicitly to make sure error messages are not
localized for testing.
