clonebundle: add a `filter_bundle_url` function

This function does nothing by default, but give extension the opportunity to
alter the URL, typically, this could be used to inject authentication token when
serving clone bundle for private repositories.

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

  merging x and y to y

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.
