update deps

The immediate motivation is that Cargo.lock referred to a commit version
in a PR branch of my nix fork that no longer exists. (I didn't know, but
it makes sense, that "git push -f" not only forcibly updates the branch
to refer to a new commit but also gets rid of orphaned commits.) Use a
moonfire branch that I'll keep stable until I'm ready to move on.

I also updated parking_lot and rusqlite to new major versions (nothing
in the interface that I care about has changed) and did a full cargo
update.
