This reverts commit 53c3046898633e56f74f7f05fb38cabeea1c87a1. This patch introduced a regression leading to a loop on the frames demultiplexing because a frame may be ignore but not consumed. But outside this regression that can be fixed, there is a design issue that was not totally fixed by the patch above. The SPOP connection state is mixed with the status of the frames demultiplexer and this needlessly complexify the connection management. Instead of fixing the fix, a better solution is to revert it to work a a proper solution. For the record, the idea is to deal with the spop connection state onlu using 'state' field and to introduce a new field to handle the frames demultiplexer state. This should ease the closing state management. Another issue that must be fixed. We must take care to not abort a SPOP stream when an error is detected on a SPOP connection or when the connection is closed, if the ACK frame was already received for this stream. It is not a common case, but it can be solved by saving the last known stream ID that recieved a ACK. This patch must be backported if the commit above is backported.
