When passing in custom driver XML, allow a block like
<domain>
...
<testdriver>
<runstate>3</runstate>
</testdriver>
</domain>
This is only read at initial driver start time, and sets the initial
run state of the object. This is handy for UI testing.
Wire it up for domains, networks, pools, and interfaces. The latter
3 only have a notion of active and inactive, which map to runstate
1 and 0 respectively.
We also take care to unlink this <testdriver> block before passing the
XML to the object parse function. Right now nothing complains, but if
XML parsing became stricter in the future we don't want it to choke
on this custom element.
