copies: replace duplicatecopies() by function that takes contexts

The callers mostly have context objects, so let's avoid looking up the
same context objects inside `duplicatecopies()`.

I also renamed the function to `graftcopies()` since I think that
better matches its purpose. I did it in the same commit so it's easier
for extensions to switch between the functions.
