copy: add experimetal support for unmarking committed copies

The simplest way I'm aware of to unmark a file as copied after
committing is this:

  hg uncommit --keep <dest>
  hg forget <dest>
  hg add <dest>
  hg amend

This patch teaches `hg copy --forget` a `-r` argument to simplify that into:

  hg copy --forget --at-rev . <dest>

In addition to being simpler, it doesn't touch the working copy, so it
can easily be used even if the destination file has been modified in
the working copy.

I'll teach `hg copy` without `--forget` to work with `--at-rev` next.
