[TWSK]: Introduce struct timewait_sock_ops
So that we can share several timewait sockets related functions and
make the timewait mini sockets infrastructure closer to the request
mini sockets one.
Next changesets will take advantage of this, moving more code out of
TCP and DCCP v4 and v6 to common infrastructure.
