cache.h: allow oid_object_info to handle arbitrary repositories
This involves also adapting oid_object_info_extended and a some internal functions that are used to implement these. It all has to happen in one patch, because of a single recursive chain of calls visits all these functions. oid_object_info_extended is also used in partial clones, which allow fetching missing objects. As this series will not add the repository struct to the transport code and fetch_object(), add a TODO note and omit fetching if a user tries to use a partial clone in a repository other than the_repository. Among the functions modified to handle arbitrary repositories, unpack_entry() is one of them. Note that it still references the globals "delta_base_cache" and "delta_base_cached", but those are safe to be referenced (the former is indexed partly by "struct packed_git *", which is repo-specific, and the latter is only used to limit the size of the former as an optimization).
