* primitive_convert converts input_buffer into output_buffer.
*
* input_buffer and output_buffer should be a string.
* output_bufsize and flags should be an integer.
* output_byteoffset should be an integer or nil.
* output_bytesize and flags should be an integer.
*
* primitive_convert convert the content of input_buffer from beginning
* and store the result into output_buffer.
*
* output_byteoffset and output_bytesize specify the region which
* the converted result is stored.
* output_byteoffset specifies the start position in output_buffer in bytes.
* If output_byteoffset is nil, output_buffer.bytesize is assumed.
* output_bytesize specifies maximum number of bytes.
* After conversion, output_buffer is resized to
* output_byteoffset + actually converted number of bytes.
*
* primitive_convert drops the first part of input_buffer.
* the dropped part is converted in output_buffer or
* buffered in Encoding::Converter object.
*
* output_buffer is resized to output_bufsize bytes at maximum.
*
* primitive_convert stops conversion when one of following condition met.
* - invalid byte sequence found in input buffer (:invalid_input)
* - character not representable in output encoding (:undefined_conversion)
