Since this is a bit ugly, consider renaming this to be NO_PARSE_ERROR.

Done.

     // Set when parsing failed due to insufficient data.
     // This error is recoverable, by passing in new data.
     NEED_MORE_DATA,
     // Set when a complete block has been read, but unprocessed data remains.
     TOO_MUCH_DATA,
     // Set when a block exceeds |MaxNumberOfHeadersForVersion| headers.
     HEADER_BLOCK_TOO_LARGE,
     // Set when a header key or value exceeds |kMaximumFieldLength|.
     HEADER_FIELD_TOO_LARGE,
     // Set when the parser is given an unexpected stream ID.
