Use io.BytesIO() instead of StringIO.StringIO().  FakeSocket still
accepts regular strings and coverts them to bytes internally.

If a makefile()-generated object is open and its parent socket is
closed, the parent socket should remain open until the child is
closed, too.  The code to support this is moderately complex and
requires one extra slots in the socket object.

This change fixes httplib so that several urllib2net test cases pass
again.

Add SocketCloser class to socket.py, which encapsulates the
refcounting logic for sockets after makefile() has been called.

Move SocketIO class from io module to socket module.  It's only use is
to implement the raw I/O methods on top of a socket to support
makefile().

Add unittests to test_socket to cover various patterns of close and
makefile.

raw socket so they can check the timeout value.  Should change the
code under test to expose the timeout in a more direct way.

Fix test_cookielib and test_urllib2.
(The changes to urllib make urllib.quote() work correctly for Unicode
strings; but they don't fix test_urllib.)

Fix for test_socketserver.
Use io.BytesIO instead of io.StringIO, and adjust tests.

Fix test_zipimport.

using super().  (See recent conversation on python-3000 with Talin
and Phillip Eby about PEP 3115 chaining rules.)

In particular, add trivial implementations of .real, .imag and .conjugate()
to both, and add .numerator and .denominator to long.
Also some small optimizations (e.g. remove long_pos in favor of long_long).

in KOI8-R.

(The previous changes to abc.py were also by him).
Put back a comment about using super() for properties
(I didn't realize this worked).

Add docstring for conjugate().
Patch by Jeffrey Yasskin.

error callback changes the bytes object in the exception the decoder might
use memory that's no longer in use. Change unicode_decode_call_errorhandler()
so that it fetches the adresses of the bytes array (start and end) from the
exception object and passes them back to the caller.

string representation for use in the XML.

Also strip out some unneeded encoding/decoding steps.

to be between str8 and str.

Reported by Joe Smith.  This makes the CYGWIN tests pass;
it's a miracle it didn't fail on other platforms.
Seems like it was accidentally dropped (maybe a merge artifact?).

encoding can only be UTF-8 now.

Unicode now.

In order to do this, I added an optional encoding argument to io.StringIO.
The toprettyxml() function returns bytes when you specify an encoding now.

Fix one of the two failing tests for minidom.

Get rid of some #ifdef'ed-out code.

Change a bunch of .assert_(X == Y) to .assertEqual(X, Y).

Fix test_aepack and test_applesingle.

Kill some dead (commented-out) code.
