REORG: Initialize the conn-stream by hand in cs_init()

The function cs_init() is only called by cs_new(). The conn-stream
initialization will be reviewed. It is easier to do it in cs_new() instead
of using a dedicated function. cs_new() is pretty simple, there is no reason
to split the code in this case.
