REVISION SUMMARY
  I'm working on support for storing copy metadata in the changeset
  instead of the filelog. I don't intend to include the file nodeid
  there, but most callers don't need that anyway. This patch introduces
  a method similar to ctx.renamed(), but the new method returns only the
  source filename, not the nodeid. Subsequent patches will move callers
  over to this new method.
