h1 parsing functions (h1_parse_msg_*) returns the number of bytes parsed or 0 if nothing is parsed because an error occurred or some data are missing. But they never return negative values. Thus, instead of a signed integer, these function now return a size_t value. The H1 and FCGI muxes are updated accordingly. Note that h1_parse_msg_data() has been slightly adapted because the parsing of chunked messages still need to handle negative values when a parsing error is reported by h1_parse_chunk_size() or h1_skip_chunk_crlf().
