Subject: [PATCH 01/35] object: add repository argument to parse_object

From: Stefan Beller <[email-masked]>
Date: Tue, 29 May 2018 17:47:36 -0700

Add a repository argument to allow the callers of parse_object
to be more specific about which repository to act on. 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.
