remove unused backend machinery
The only remaining vestiage of backends is different types of keys. These are still called "backends", mostly to avoid needing to change user interface and configuration. But everything to do with storing keys in different backends was gone; instead different types of remotes are used. In the refactoring, lots of code was moved out of odd corners like Backend.File, to closer to where it's used, like Command.Drop and Command.Fsck. Quite a lot of dead code was removed. Several data structures became simpler, which may result in better runtime efficiency. There should be no user-visible changes.
