[net-next 4/4] tipc: tipc: rename address types in user api

[Jon Maloy <jon.maloy@ericsson.com>]

The three address type structs in the user API have names that in
reality reflect the specific, non-Linux environment where they were
originally created.

We now give them more intuitive names, in accordance with how TIPC is
described in the current documentation.

struct tipc_portid   -> struct tipc_socket_addr
struct tipc_name     -> struct tipc_service_addr
struct tipc_name_seq -> struct tipc_service_range

For compatibility, we add macros that map the old names to the new ones.
