Re: [Libvir] PATCH: Cleanup generator & force build fail on missing APIs

The python generator will happily ignore functions it can't handle and pretend everything completed without error. This leads to the situation where we add new APis to C library and no one ever notices that they are missing from the python until months later. This requires that my previous patch be applied first to implement the missing APIs we already have :-) This patch causes the generator to return a non-zero exit status if there are any APIs marked as FAILED. It will also explicitly print out their names so its clear what is missing. In doing this I added a bunch more functions to the skip list - ones that we already manually wrote.
