Wow, I did not plan to remove direct mode today! The original plan was to work on sqlite database improvements. But that seems to need a v8 repository format, to avoid confusing old git-annex with the new db schemas. And to get to v8, we must first get to v7..

Removing direct mode eliminated over 1000 lines of code. I may be able to remove a few hundred more yet.

Did find a bug with the upgrade process just as I was wrapping up for the day, it's minor (involving a deleted file in the work tree), so I'll deal with it tomorrow.
