[PATCH 11/19] replace-object: add repository argument to do_lookup_replace_object

[Stefan Beller <sbeller@google.com>]

Add a repository argument to allow the do_lookup_replace_object caller
to be more specific about which repository to handle. This is a small
mechanical change; it doesn't change the implementation to handle
repositories other than the_repository yet.

As with the previous commits, use a macro to catch callers passing a
repository other than the_repository at compile time.
