Python 2/3 compatibility definitions.

This module currently provides the following helper symbols:

* bytes (name of byte string type; str in 2.x, bytes in 3.x)
* b (function converting a string literal to an ASCII byte string;
  can be also used to convert a Unicode string into a byte string)
* u_prefix (unicode repr prefix: 'u' in 2.x, '' in 3.x)
  (Required in docutils/test/test_publisher.py)
* BytesIO (a StringIO class that works with bytestrings)
