SPDY: fixed potential integer overflow while parsing headers. Previously r->header_size was used to store length for a part of value that represents an individual already parsed HTTP header, while r->header_end pointed to the end of the whole value. Instead of storing length of a following name or value as pointer to a potential end address (r->header_name_end and r->header_end) that might be overflowed, now r->lowercase_index counter is used to store remaining length of a following unparsed field. It also fixes incorrect $body_bytes_sent value if a request is closed while parsing of the request header. Since r->header_size is intended for counting header size, thus abusing it for header parsing purpose was certainly a bad idea.
