Nut upsdev - Feb 2013 - bcmxcp branch

There are some useful commits on the bcmxcp branch, but it is several years old,
and it won't merge cleanly.

I don't mind sorting out the merge issues, but I would like someone to test
it when I'm done. (I don't have any BCM/XCP-based hardware.) Any
volunteers?

Here's the overview:
