During H1 parsing, the HTX EOM block is added before switching the message state to H1_MSG_DONE. It is an exception in the way to convert an H1 message to HTX. Except for this block, the message is first switched to the right state before starting to add the corresponding HTX blocks. For instance, the message is switched in H1_MSG_DATA state and then the HTX DATA blocks are added. With this patch, the message is switched to the H1_MSG_DONE state when all data blocks or trailers were processed. It is the caller responsibility to call h1_parse_msg_eom() when the H1_MSG_DONE state is reached. This way, it is far easier to catch failures when the HTX buffer is full. The H1 and FCGI muxes have been updated accordingly. This patch may eventually be backported to 2.1 if it helps other backports.
