Add vxlan destination port option

Add ability to set UDP destination port on a per device basis.
If no port is assigned, the default IANA assigned port will be used.
If you want the kernel default value, then use port 0.

Source port range option is now called 'srcport', to avoid
confusion. The old option syntax is accepted for compatiablity.
