When we are waiting for the server response, if an error is pending on the frontend side (a write error on client), it is handled as an abort and all regular response analyzers are removed, except the one responsible to release the filters, if any. However, while it is handled as an abort, the error is not reported, as usual, via http_reply_and_close() function. It is an issue because in that, the channels buffers are not reset. Because of this bug, it is possible to block a stream infinitely. The request side is waiting for the response side and the response side is blocked because filters must be released and this cannot be done because data remain blocked in channels buffers. So, in that case, calling http_reply_and_close() with no message is enough to unblock the stream. This patch must be backported as far as 2.8.
