This patch introduces a proc file cio_settle. A write request to
this file is blocked until all queued cio actions are handled.
This will allow userspace to wait for pending work affecting
device availability after changing cio_ignore or the hardware
configuration.

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!
