Since the @dconn reference via args->conn will be used via a thread
or callback, let's make sure memory associated with it isn't free'd
unexpectedly before we use it. The Unref will be done when the object
is Dispose'd.

When adding the @vm to the @args for usage during a thread or
callback, let's add the reference to it at the time of adding to
ensure nothing else deletes it. The corresponding Unref is then
added to the Dispose function.

Use the FindBy{UUID|Name}Locked helpers which will return a locked
and ref counted object rather than the direct virHashLookup and
virObjectLock of the returned object. We'll need to temporarily
virObjectUnref when we assign a new domain @def, but that will
change shortly when virDomainObjListAddObjLocked returns the
correct reference counted object.
Use the virDomainObjEndAPI in the error path to Unref/Unlock for
the corresponding Unref/Unlock of either the FindBy* return or
the virDomainObjNew since both return a reffed/locked object.

<features><vmcoreinfo/> is a bare boolean XML property. We don't really
use this format anymore and instead prefer tristate <X state=on|off/>
since it's required for modeling on/off/default. If for example future
qemu started enabling vmcoreinfo by default we wouldn't have any way
for the user to turn this off.
Convert it to tristate. For writing XML this is semanticly the same,
<vmcoreinfo/> is processed as <vmcoreinfo state='on'/>.
For apps reading guest XML this is technically an API change,
as they might misinterpret <vmcoreinfo state='off'/>, however this
has only been present in libvirt since 3.10.0 and I don't think any
apps are dependent on this yet

The virDomainNet struct contains everything related to configuring a

relevant to configuring network filters. It will be more convenient for
