Adds a new interface type using UDP sockets, this seems only applicable to QEMU but have edited tree-wide to support the new interface type.
The interface type required the addition of a "destaddr" (destination address), this then maps into the following xml and qemu call.
<interface type='udp'> <mac address='52:54:00:5c:67:56'/> <source address='127.0.0.1' port='11112'/> <model type='virtio'/> <dest address="127.0.0.1' port='22222'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> ...
QEMU call: -netdev socket,udp=127.0.0.1:22222,localaddr=127.0.0.1:11112
Notice the xml "source" entry becomes the "localaddr" for the qemu call.

It would be nice to document what the addresses mean, and mention that this is supported <span class="since">Since 1.2.19</span>. Jan
