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

[Stefan Beller <sbeller@google.com>]

From: Jonathan Nieder <jrnieder@gmail.com>

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.
