REORG: stream/backend: move backend-specific stuff to backend.c

For more than a decade we've kept all the sess_update_st_*() functions
in stream.c while they're only there to work in relation with what is
currently being done in backend.c (srv_redispatch_connect, connect_server,
etc). Let's move all this pollution over there and take this opportunity
to try to find slightly less confusing names for these old functions
whose role is only to handle transitions from one specific stream-int
state:

  sess_update_st_rdy_tcp() -> back_handle_st_rdy()
  sess_update_st_con_tcp() -> back_handle_st_con()
  sess_update_st_cer()     -> back_handle_st_cer()
  sess_update_stream_int() -> back_try_conn_req()
  sess_prepare_conn_req()  -> back_handle_st_req()
  sess_establish()         -> back_establish()

The last one remained in stream.c because it's more or less a completion
function which does all the initialization expected on a connection
success or failure, can set analysers and emit logs.

The other ones could possibly slightly benefit from being modified to
take a stream-int instead since it's really what they're working with,
but it's unimportant here.
