repair: begin implementation of in-place upgrading

Now that all the upgrade planning work is in place, we can start
doing the real work: actually upgrading a repository.

The main goal of this commit is to get the "framework" for running
in-place upgrade actions in place.

Rather than get too clever and low-level with regards to in-place
upgrades, our strategy is to create a new, temporary repository,
copy data to it, then replace the old data with the new. This allows
us to reuse a lot of code in localrepo.py around store interaction,
which will eventually consume the bulk of the upgrade code.

But we have to start small. This patch implements adding new
repository requirements. But it still sets up a temporary
repository and locks it and the source repo before performing the
requirements file swap. This means all the plumbing is in place
to implement store copying in subsequent commits.
