Port: Stricter port bind/unbind semantics
This patch tightens up the semantics around port binding and checks that the ports that are being bound are currently not connected, and similarly connected before unbind is called. The patch consequently also changes the order of the unbind and bind for the switching of CPUs to ensure that the rules are adhered to. Previously the ports would be "over-written" without any check. There are no changes in behaviour due to this patch, and the only place where the unbind functionality is used is in the CPU.
