[virt-tools-list] [PATCH virt-viewer 1/2] virt-viewer: Support newer libvirt xml format

[Pavel Grunt]

Since libvirt 0.9.4 there is a new listen element which can be used
to specify address instead of using the attributes of graphics element.

Also add support for listen type socket - available for Qemu since
libvirt 2.0.0

Resolves: rhbz#1411765
