[MEDIUM] move connection establishment from backend to the SI.
The connection establishment was completely handled by backend.c which
normally just handles LB algos. Since it's purely TCP, it must move to
proto_tcp.c. Also, instead of calling it directly, we now call it via
the stream interface, which will later help us unify session handling.
