UNUSED blocks were not properly handled when the H1 multiplexer was formatting the start line of a request or a response. UNUSED was ignored but not removed from HTX message. So the mux can loop infinitly on such block. It could be seen a a major issue but in fact it happens only if a very specific case on the reponse processing (at least I think so): the server must send an interim message (a 100-continue for intance) with the final response. HAProxy must receive both in same time and the final reponse must be intercepted (via a http-response return action for instance), In that case, the interim message is fowarded and the server final reponse is removed and replaced by a proxy error message. Now UNUSED htx blocks are properly skipped and removed. This patch must be backported as far as 3.0.
