MEDIUM: stream-int: make sure to try to immediately validate the connection
In the rare case of immediate connect() (unix sockets, socket pairs, and
occasionally TCP over the loopback), it is counter-productive to subscribe
for sending and then getting immediately back to process_stream() after
having passed through si_cs_process() just to update the connection. We
already know it is established and it doesn't have any handshake anymore
so we just have to complete it and return to process_stream() with the
stream_interface in the SI_ST_RDY state. In this case, process_stream will
simply loop back to the beginning to synchronize the state and turn it to
SI_ST_EST/ASS/CLO/TAR etc.
This will save us from having to needlessly subscribe in the connect()
code, something which in addition cannot work with edge-triggered pollers.
