some of the more compilcated cases (CF, Res) haven't been done yet. Also,
various types should inherit from each other (anything with an as_Resource
method should be a Resource subtype, the CF types should become one family).

descriptors in stead of manual getattr hooks to get at attributes
of the objects.

For Qd I have in stead gotten rid of most of the attribute access
in favor of the carbon-style accessor methods (with the exception
of visRgn, to be done later), and of the Carbon.Qd.qd global object,
for which accessor functions are also available.

For List I have fixed the fact that various methods were incorrectly
generated as functions.

CF is untouched: PEP252 doesn't allow "poor-mans-inheritance" with
basechain, so it will have to wait for PEP253 support.

Weaklink most toolbox modules, improving backward compatibility. Modules will no longer fail to load if a single routine is missing on the curent OS version, in stead calling the missing routine will raise an exception.

Should finally fix 531398. 2.2.1 candidate.

- print traceback
- don't use fprintf()
- clear exception (implied by PyErr_Print())

The MacOS toolbox modules have acquired an _ in front of their name. Normal usage is through a wrapper module (without underscore) which lives in the Carbon package.

Lots more Carbon/Carbon.h includes, new UPP routine names, function prototypes. Most toolbox modules now compile, link and import in MacOSX-MachO python.

First step in porting MacPython modules to OSX/unix: break all references between modules except for the obj_New() and obj_Convert() routines, the PyArg_Parse and Py_BuildValue helpers.

And these can now be vectored through glue routines (by defining USE_TOOLBOX_OBJECT_GLUE) which will do the necessary imports, whereupon the module's init routine will tell the glue routine about the real conversion routine address and everything is fine again.

functions. Include it in stead of duplicating the declarations everywhere. Also
cleaned up toolbox module exports, and got rid of resNotFound error.
