[issue18886] BytesGenerator does not handle 'binary' CTE correctly

[R. David Murray]

New submission from R. David Murray:

ByteGenerator will assume that it can change any linesep characters to the linesep being used for the general message serialization, even if the content transfer encoding is 'binary'.  This is incorrect, as existing \r and \n characters in binary parts must be retained exactly as is.
