[PATCH 082/194] object: add repository argument to lookup_object




From: Jonathan Nieder <jrnieder@xxxxxxxxx>

Add a repository argument to allow callers of lookup_object 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.

The included coccinelle semantic patch will adapt any new callers in
the diff produced by `make coccicheck`.
