Merging to the CEDET repo is not needed, since we will abandon it

I think it will be less work to simply do the diff|patch game and fixing
a few paths along the way. Since the histories are unrelated, git cannot
really help you with the merges anyway.

I wouldn't worry too much about the history of the tests. The authorship
of the changes should be clear, but at least I don't care much for
granularity here.
