[PATCH 06/26] IPVS: Add IPv6-specific function pointers to struct ip_vs_protocol.

["Julius R. Volz" <juliusv@google.com>]

Add some IPv6-specific handler function pointers to struct ip_vs_protocol.
These are needed for handlers that (may) have a different implementation
between protocol versions. Depending on the code path (processing either
v4 or v6 packets), the corresponding version of a handler will be called.
