Re: [PATCH 5/5] read_loose_refs(): read refs using resolve_ref_recursively()

> There is no need to call read_ref_full() or resolve_gitlink_ref() from
> read_loose_refs(), because we already have a ref_store object in hand.
> So we can call resolve_ref_recursively() ourselves. Happily, this
> unifies the code for the submodule vs. non-submodule cases.

> This requires resolve_ref_recursively() to be exposed to the refs
