C++/DUchain problems after latest changes

[Andreas Pakulat]

Hi,

First of all: The build was broken, make krossWrappers didn't work
anymore, hence the generated code cannot be updated and there was an API
change in the language library which makes the comitted code not link
anymore. Running make krossWrappers simply returned an error and the "well
known" messages:
,----
| <unknown program name>(10487)/
| KDevelop::allocateGlobalItemRepositoryRegistry: making
| "/home/andreas/.kdevduchain/0"
| <unknown program name>(10487)/
| KDevelop::allocateGlobalItemRepositoryRegistry: picked duchain directory
| "/home/andreas/.kdevduchain/0"
| <unknown program name>(10487)/ KDevelop::ItemRepositoryRegistry::open:
| "/home/andreas/.kdevduchain/0/version_38" not found, seems to be an old
| version
| <unknown program name>(10487)/ KDevelop::ItemRepositoryRegistry::open: "The
| data-repository at /home/andreas/.kdevduchain/0 has to be cleared. Either
| the disk format has changed, or KDevelop crashed while writing the
| repository"
`----

It seems I was able to "fix" that by starting up kdevelop once, make
krossWrappers works now but it seems to be a lot slower than it was last
time I ran it.

Also I get those messages from duchain-repository everytime the duchain is
loaded, even after a rm -rf $HOME/.kdevduchain.

Last but not least: I'm also getting this after a full rebuild when closing
kdevelop (backtrace at the end):
