Instead of hashing headers, define an interop version. Do not mount
superblocks that have a different version, either higher or lower.
Since this is pretty much the same as the format hash except it's a
constant, minimal code changes are needed.
Initial dev version is 0, with the intent that version will be bumped to
1 immediately prior to tagging initial release version.
Update README. Fix comments.
Add interop version to notes and modinfo.

Move the main scoutfs README.md from the old kmod/ location into the top
of the new single repository. We update the language and instructions
just a bit to reflect that we can checkout and build the module and
utilities from the single repo.
