TARGET_API_MAC_OS8 (or !TARGET_API_MAC_CARBON) is gone. Also some
TARGET_API_MAC_OSX conditional code is gone, because it is no longer
used on OSX-only Python (only in MacPython-OS9).

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.

Don't blacklist ModalFilterUPP but always pass it as NULL. This enables the record routines to be generated.

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.

Changed all (hopefully) uses of unsigned 16 bit value to use H format specifier, now that h is signed-only.

sound-output interface, so this needs a Python wrapper shortly.

- Use Universal Headers as input
- Change addpack calls to not depend on Guido's disklayout
- Checkge testprograms to use new names for some functions
