Instead of using global variables to store promisor remote information,
store this config in struct repository instead, and add
repository-agnostic non-static functions corresponding to the existing
non-static functions that only work on the_repository.
The actual lazy-fetching of missing objects currently does not work on
repositories other than the_repository, and will still not work after
this commit, so add a BUG message explaining this. A subsequent commit
will remove this limitation.
