Subject: [PATCH 22/44] sha1_file: add repository argument to stat_sha1_file

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Sat, 3 Mar 2018 18:36:15 +0700

From: Stefan Beller <[email-masked]>

Add a repository argument to allow the stat_sha1_file caller 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.
