MINOR: connection: Add a function to detach a conn-stream from the connection

Browse Source 
cs_detach() function is added to detach a conn-stream from the underlying
connection. This part will evovle to handle applets too. Concretely,
cs_destroy() is split to detach the conn-stream from its endpoint, via
cs_detach(), and then, the conn-stream is released, via cs_free().
