Can we wait until we bring the common/of stuff back from the tmp
branch? It'll make the changes to the openib BTL significantly
easier to merge.

I don't know Torsten's/Gleb's timeframe for moving everything to
common/of -- my job was to provide the skeleton and I did so. :-)

Yes, I very much care about backward compatibility of the openib name
and MCA parameters... This is, as I see it, the biggest issue with
changing the name. Stuff like this has to work:

        mpirun --mca btl openib,self ...
        mpirun --mca btl_openib_foo 32 ...
