rawdata: implement `rawdata` for `simplestore` too

This is needed for all implementation.

Copy a file, then delete destination, then copy again. This does not create a new filelog entry.

Copy x to y, then remove y, then add back y. With copy metadata in the
changeset, this could easily end up reporting y as copied from x (if we don't
unmark it as a copy when it's removed). Despite x and y not being related, we
want grafts to propagate across the rename.

Add x, remove it, then add it back, then rename x to y. Similar to the case
above, but here the break in history is before the rename.

the break.
