[PATCH 15/39] object-store: add repository argument to prepare_alt_odb

[Jonathan Nieder <jrnieder@gmail.com>]

From: Stefan Beller <sbeller@google.com>

Add a repository argument to allow prepare_alt_odb callers 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.

While at it, move the declaration to object-store.h, where it should
be easier to find.
