The CLOSING state was not handled at all by the SPOP multiplexer while it is mandatory when a DISCONNECT frame was sent and the mux should wait for the DISCONNECT frame in reply from the agent. Thanks to this patch, it should be fixed. In addition, if an error occurres during the AGENT HELLO frame parsing, the SPOP connection is no longer switched to CLOSED state and remains in ERROR state instead. It is important to be able to send the DISCONNECT frame to the agent instead of closing the TCP connection immediately. This patch depends on following commits: * BUG/MEDIUM: mux-spop: Remove frame parsing states from the SPOP connection state * MINOR: mux-spop: Don't set SPOP connection state to FRAME_H after ACK parsing * BUG/MINOR: mux-spop: Don't open new streams for SPOP connection on error * BUG/MINOR: mux-spop: Make the demux stream ID a signed integer All the series must be backported to 3.1.
