This series of patches does two things. First, it starts to give up on the idea
that you can run FooBSD binaries on BarBSD. They are too different to make that
happen any time soon, though I've kept the support for Net/OpenBSD, even though
they haven't built. We'll need a lot of work to make that happen, though, and
I need to simplify to get things upstream.

Second, this upstreams the first 9 system calls. It deletes the old
implementation and starts fresh with a new one that pulls some things from the
old, updates some old things, etc. It's easier to understand this way.

Finally, it starts to move some of the ifdef trees into target.h.
