When the destination buffer is full while there are still data to parse, the h1s must be marked as congested to be able to restart the parsing later. This work on headers and data parsing. But on trailers parsing, we fail to do so when the buffer is full before to parse the trailers. In this case, we skip the trailers parsing but the h1s is not marked as congested. This is important to be sure to wake up the mux to restart the parsing when some room is made in the buffer. Because of this bug, the message processing may hang till a timeout is triggered. Note that for 2.3 and 2.2, the EOM processing is buggy too, for the same reason. It should be fixed too on these versions. On the 2.0, only trailers parsing is affected. This patch must be backported as far as 2.0. On 2.3 and 2.2, the EOM parsing must be fixed too.
