[PATCH 09/39] sha1_file: add repository argument to read_info_alternates

[Jonathan Nieder]

From: Stefan Beller <sbel...@google.com>

Add a repository argument to allow the read_info_alternates caller to
be more specific about which repository to read from. This is a small
mechanical change; it doesn't change the implementation to handle
repositories other than the_repository yet.

As with the previous commit, use a macro to catch callers passing a
repository other than the_repository at compile time.
