Subject: [PATCHv2 5/9] packfile: add repository argument to packed_object_info

From: Stefan Beller <[email-masked]>
Date: Tue, 24 Apr 2018 14:59:05 -0700

From: Jonathan Nieder <[email-masked]>

Add a repository argument to allow callers of packed_object_info 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.
