[PATCHv3 6/9] packfile: add repository argument to read_object

From: Stefan Beller <sbeller@google.com>

Message-ID: <20180425182106.162972-7-sbeller@google.com>
In-Reply-To: <20180425182106.162972-1-sbeller@google.com>

Add a repository argument to allow the callers of read_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.
