Ok, I have now committed these files, and patched Kate (in kdebase) to use 
them as proof-of concept.

The last remaining deficiencies that I am aware of are:
- namespaces with exported functions do not have forwarding headers generated 
for them, e.g. KStdAccel, KStdAction etc.
- I have not (yet?) created catchall includes, eg. like with Qt you can do 
#include <QtGui>

For the moment, if small changes are needed you can make them by hand, or ask 
me to regenerate the includes.  Sometime soon hopefully the cmake change will 
get merged and anyone will be able to perform the generation.
