Alexander Larsson ce9d889436 Change how ChangesDirs() works ...

Rather than scan the files in the old directory twice to detect the
deletions we now scan both directories twice and then do all the
diffing on the in-memory structure.

This is more efficient, but it also lets us diff more complex things
later that are not exact on-disk trees.
