MINOR: htx: Add a flag on HTX message to report processing errors
This new flag may be used to report unexpected error because of not well
formatted HTX messages (not related to a parsing error) or our incapactity to
handle the processing because we reach a limit (ressource exhaustion, too big
headers...). It should result to an error 500 returned to the client when
applicable.
