In case of variable 'oldjob' (job structure) in
qemuProcessReconnect() the cb pointer was just copied from the
existing job structure in virDomainObjPreserveJob(). This caused
the job and oldjob sharing the same pointer, which was later
freed at the end of the qemuProcessReconnect() function by
automatic call to virDomainObjClearJob(). This caused an invalid
read in and subsequent daemon crash as the job structure was
trying to read cb which had been already freed.
This patch changes the copying to g_memdup that allocates
different pointer, which can be later safely freed.

The 'cb' and 'jobDataPrivateCb' pointers are stored in the job object
but made point to the memory owned by the virDomainXMLOption struct in
the callers.
Since the 'virdomainjob' module isn't in control the lifetime of the
virDomainXMLOption, which in some cases is freed before the domain job
data, freed memory would be dereferenced in some cases.
Copy the structs from virDomainXMLOption to ensure the lifetime. This is
possible since the callback functions are immutable.

Adding supposedly secure cleanup for secrets in anything related to the
XML parser is pointless because there are multiple other un-sanitized
copies of the full XML and the XML parser state at the very least.
Similarly in case RPC was used to transport the XML the RPC buffers are
not sanitized.
Additionally this patch was incomplete as it didn't sanitize the
password in the cleanup function for virDomainGraphicsAuthDef.

Since we've never formatted '-1' into an XML formatted by libvirt we can

It would be nice to be able to test the mediated device capabilities
without having physical hardware which supports it. The 'mtty' kernel
module presents a virtual parent device which is capable of creating
'fake' mediated devices, and as such it would be useful for testing.
However, the 'mtty' device is not part of an existing device subsystem
(e.g. PCI, etc), so libvirt ignores it and it does not get added to the
node device list. And because it does not get added to the node device
list, it cannot be used to create child mdevs using `virsh
nodedev-create`.
There is already a node device type capability
VIR_NODE_DEV_CAP_MDEV_TYPES that indicates whether a device supports
creating child mediated devices, but libvirt assumes that this is a
nested capability (in other words, it assumes that the primary
capability of a device is something like PCI). If we allow this
MDEV_TYPES capability to be a primary device capability, then we can
support virtual devices like 'mtty' as a parent for mediated devices.
