Even though it's auto-generated it's based on qemu.conf option and listen type address already uses "fromConfig" to carry this information. Following commits will convert the socket to listen element so this rename is required because there will be also an option to get socket auto-generated independently on the qemu.conf option.

This moves the socket generation if "vnc_auto_unix_socket" is set. It also fixes a bug with this config option that we should auto-generate socket path only if listen type is address and there is no address specified.

VNC graphics already supports sockets but only via 'socket' attribute. This patch coverts that attribute into listen type 'socket'. For backward compatibility we need to handle listen type 'socket' and 'socket' attribute properly to support old XMLs and new XMLs. If both are provided they have to match, if only one of them is provided we need to be able to parse that configuration too. To not break migration back to old libvirt if the socket is provided by user we need to generate migratable XML without the listen element and use only 'socket' attribute.

This new listen type is currently supported only by spice graphics. It's introduced to make it easier and clearer specify to not listen anywhere in order to start a guest with OpenGL support. The old way to do this was set spice graphics autoport='no' and don't specify any ports. The new way is to use <listen type='none'/>. In order to be able to migrate to old libvirt the migratable XML will be generated without the listen element and with autoport='no'. Also the old configuration will be automatically converted to the this listen type.
