[Kde-bindings] twine2 (PyKDE5 code generator) parsing issues

[Luca]

Hello Scott,
I did some tests and I was able to build easily kconfig.

The KCOREADDONS_DEPRECATED must be added to the qtkde5macros script. I 
attached a patch I created, so you have an idea what I did.

For the other errors are very specific.
I found for instance that pointer are not handled correctly, and throw an 
error.

Also this line is problematic:
typedef void (QObject::* NotifyFunction)(quint64 arg);

Seems also that also this line is not handled:
#ifndef KDE_NO_DEPRECATED
I looked in pplexer.py but seems that the #ifndef definition is managed, don't 
know why this generates an error.

You are working on the official repository?
I'm personally testing locally, I need this lib to port our SW to kf5 on 
Chakra linux.

Luca
