Marcus Huewe caaefb0bf5 Fix and simplify util.safewriter.SafeWriter
Storing the error encoding in an "encoding" attribute "breaks" the
python3 "input" function: In essence, builtin_input_impl does a
getattr(sys.stdout, 'encoding'), which returns our error encoding
instead of the "real" stdout encoding. In order to avoid this, we
store the error encoding in an "_encoding" attribute.

Making SafeWriter a new-style class simplifies the code a lot.
