Interface moves and renames merged on rtt/ocl master branches

I have tested and pushed the renames Markus did to the gitorious
rtt/ocl master branches.

If it doesn't compile, check that no old headers are used on your system.

The only thing left is moving the ports into the Service, which will
be transparent, since the existing ports() / addPort() functions
remain in place, it's the internal storage of the TaskContext that
changes. And that provides("foo")->addPort( barport, "bar") will be
now legal too. TaskBrowser won't be able to connect the ports of child
services right away though, code needs to be added to take care of
that.

I have also some other ocl/rtt cleanup patches lying around which I
won't merge until monday, since they are too far out of my reach right
now.
