Fortunately it's rarely called; only the gdb 'pyo' command seems affected.

Completely get rid of StringIO.py and cStringIO.c.

I had to fix a few tests and modules beyond what Christian did, and
invent a few conventions.  E.g. in elementtree, I chose to
write/return Unicode strings whe no encoding is given, but bytes when
an explicit encoding is given.  Also mimetools was made to always
assume binary files.

The problem is that ctypes c_char (and c_char_p) creates unicode string
instead of byte string. I attached a proposition (patch) to change this
behaviour (use bytes for c_char).

So in next example, it will display 'bytes' and not 'str':
  from ctypes import c_buffer, c_char
  buf = c_buffer("abcdef")
  print (type(buf[0]))

Other behaviour changes:
 - repr(c_char) adds a "b"
   eg. repr(c_char('x')) is "c_char(b'x')" instead of "c_char('x')"
 - bytes is mutable whereas str is not:
   this may break some modules based on ctypes

The HTTPResponse object is being passed to BufferedReader, but it
wasn't designed to be used that way.  These changes extend the hacks
that have already been made in urllib2 to get the tests to pass.

The hacks need to be removed and proper support for use with the io
library.  That's a project for another day.

(I'm not sure about it actually working though.)
