In a process with multiple repositories open, packfile accessors should be associated to a single repository and not shared globally. Move packed_git and packed_git_mru into the_repository and adjust callers to reflect this. Patch generated by 1. Moving the struct packed_git declaration to object-store.h and packed_git, packed_git_mru globals to struct object_store. 2. Apply the following semantic patch to adjust callers: @@ @@ - packed_git + the_repository->objects.packed_git @@ @@ - packed_git_mru + the_repository->objects.packed_git_mru 3. Applying line wrapping fixes from "make style" to break the resulting long lines. 4. Adding missing #includes of repository.h where needed. 5. As the packfiles are now owned by an objectstore, which is ephemeral unlike globals, we introduce memory leaks. So address them in raw_object_store_clear(). Defer freeing packed_git to the next patch due to the size of this patch.
