This is the first patch in the series where I don't immediately agree
with the patch. This is a big list of methods that don't seem like
they fit in repository.h:

The goal to remove repository.h from hash.h and object.h makes sense
as a goal, but is there another way to do it? Can we redefine
'extern struct repository *the_repository;' in hash.h so we have
access to that pointer?
Thanks,
