Providing compatibility to various old-school Unix systems from the 1990s
was fun 25 years ago, but today it just attracts automated bug checkers
that have no point in something like this used for retro-computing.

As there as only one known users (and contributor) in the last 15 years,
drop it.  Anyone who needs to access such a file system can stay on an
older kernel, or maintain the code out of tree as it doesn't require
anything fancy.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
