Fixes the problem reported in bug #438786.

Removed all instances of Py_UCS2 from the codebase, and so also (I hope)
the last remaining reliance on the platform having an integral type
with exactly 16 bits.
PyUnicode_DecodeUTF16() and PyUnicode_EncodeUTF16() now read and write
one byte at a time.

Add wrappers to expose "floor" and "true" division.

uninstantiable.  All is well now.

inherited unless *both*: (a) the base type is 'object', and (b) the
subtype is not a "heap" type.

bit.  For one, this class:

    class C(object):
        def __new__(myclass, ...): ...

would have no way to call the __new__ method of its base class, and
the workaround (to create an intermediate base class whose __new__ you
can call) is ugly.

So, I've come up with a better solution that restores object.__new__,
but still solves the original problem, which is that built-in and
extension types shouldn't inherit object.__new__.  The solution is
simple: only "heap types" inherit tp_new.  Simpler, less code,
perfect!

repr(type(x)).

  Previously, f.read() and f.readlines() checked for
  errors on their file object and possibly raised an
  IOError, but f.readline() didn't. This patch makes
  f.readline() behave like the others.

Note that I've added a call to clearerr() since the other calls to
ferror() include that too.

I have no way to test this code. :-)

Look specific to Windows.  Don't know whether it works.

  For local files urllib.py doesn't return the MIME
  headers that the documentation says it does:

  http://www.python.org/doc/current/lib/module-
  urllib.html#l2h-2187 states that "When the method is
  local-file, returned headers will include a Date
  representing the file's last-modified time, a Content-
  Length giving file size, and a Content-Type containing
  a guess at the file's type"

  But in Python 2.1 the only header that gets returned
  is the Content-Type:

  >>> import urllib
  >>> f = urllib.urlopen("gurk.txt")
  >>> f.info().headers
  ['Content-Type: text/plain\n']

string.join() on each invocation of _bind.

Python's logolike module turtle.py did not display
the turtle except when actually drawing lines.
This patch changes the turtle.py module so that
it displays the turtle at all times when tracing is
on. This is similar to the the way that logo works.
When tracing is off the turtle will not be displayed.

get_referents, and is not yet documented in the library manual).
Suggestions for a better name welcome.

If multiple header files are processed simultaneously which include each
other, the corresponding modules mport each other. Specifically, if h2py
is invoked with sys/types.h first, later header files won't contain the
complete contents of TYPES.py.

(This file could stand some reorganization -- it's hard to tell the
open items apart from those that are done or nearly done.)
