scmutil: add a function to mark that files have been operated on

Several places use scmutil.addremove as a means to declare that certain files
have been operated on. This is ugly because:
- addremove takes patterns relative to the cwd, not paths relative to the root,
  which means extra contortions for callers.
- addremove doesn't make clear what happens to files whose status hasn't
  changed.

This new method accepts filenames relative to the repo root, and has a much
clearer contract. It also allows future modifications that do more with files
whose status hasn't changed.
