SF patch 568629 by Oren Tirosh: types made callable.

Browse source 
These built-in functions are replaced by their (now callable) type:

    slice()
    buffer()

and these types can also be called (but have no built-in named
function named after them)

    classobj (type name used to be "class")
    code
    function
    instance
    instancemethod (type name used to be "instance method")

The module "new" has been replaced with a small backward compatibility
placeholder in Python.

A large portion of the patch simply removes the new module from
various platform-specific build recipes.  The following binary Mac
project files still have references to it:

    Mac/Build/PythonCore.mcp
    Mac/Build/PythonStandSmall.mcp
    Mac/Build/PythonStandalone.mcp

[I've tweaked the code layout and the doc strings here and there, and
added a comment to types.py about StringTypes vs. basestring.  --Guido]
