[libvirt] [gconfig v2 4/6] config: Add vnc listen getter/setter

[Visarion Alexandru]

From: Visarion Alexandru <viorel.visarion at gmail.com>

Learn to get/set the listen devices that vnc is using.

When setting the listen devices, first remove the 'listen' attribute
to avoid inconsistencies checks between the 'listen' attribute and the
'address' attribute of the 'listen' node.
