Code and design clean-up for the refs API.

* mh/submodule-hash:
  read_loose_refs(): read refs using resolve_ref_recursively()
  files_ref_store::submodule: use NULL for the main repository
  base_ref_store_init(): remove submodule argument
  refs: push the submodule attribute down
  refs: store submodule ref stores in a hashmap
  register_ref_store(): new function
  refs: remove some unnecessary handling of submodule == ""
  refs: make some ref_store lookup functions private
  refs: reorder some function definitions
