Subject: [PATCH 12/19] replace-object: add repository argument to lookup_replace_object

From: Stefan Beller <[email-masked]>
Date: Fri, 6 Apr 2018 16:21:29 -0700

Add a repository argument to allow callers of lookup_replace_object
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.
