This is a cleanup commit. It assembles all tunnel outer updates into one function call to avoid code duplications. It defines RTE_VXLAN_GPE_DEFAULT_PORT (4790) in accordance with all other tunnel protocol definitions. It replaces all numeric values 4789 in their corresponding definition RTE_VXLAN_GPE_DEFAULT_PORT. It updates the 'csum parse-tunnel' documentation.
