VXLAN over IPv6.

Browse Source 
Refactors the VXLAN node to work with both IPv4 and IPv6 transports.

There is a discussion thread for this change at
https://lists.fd.io/pipermail/vpp-dev/2016-March/000279.html

Note that this changes the binary configuration API to support both
address families; each address uses the same memory for either address
type and a flag to indicate which is in use. This also includes changes
to the Java API to support both address families.

The CLI and VAT syntax remains unchanged; the code detects whether an
IPv4 or an IPv6 address was given.

Configuration examples:

IPv4 CLI: create vxlan tunnel src 192.168.1.1 dst 192.168.1.2
                vni 10 encap-vrf-id 0 decap-next l2
IPv6 CLI: create vxlan tunnel src 2620:124:9000::1 dst 2620:124:9000::2
                vni 16 encap-vrf-id 0 decap-next l2

IPv4 VAT: vxlan_add_del_tunnel src 192.168.1.1 dst 192.168.1.2
                vni 10 encap-vrf-id 0 decap-next l2
IPv6 VAT: vxlan_add_del_tunnel src 2620:124:9000::1 dst 2620:124:9000::2
                vni 16 encap-vrf-id 0 decap-next l2

TODO: The encap path is not as optimal as it could be.
