[libvirt] [libvirt-glib 05/20] config: Add spice listen getter/setter

[Christophe Fergeau]

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

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

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