MEDIUM: stream: Allocate backend CS when the stream is created

Browse Source 
Because the backend conn-stream is no longer released during connection
retry and because it is valid to have conn-stream with no connection, it is
possible to allocated it when the stream is created. This means, from now, a
stream has always valid frontend and backend conn-streams. It is the first
step to merge the SI and the CS.
