Resend using accessors instead of volatile qualifiers per hch comments, and
easier to understand convenience macros per rja comments.
Patch to apply volatile semantics when accessing MMR's in various SN files.

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!
