refs: pass repo when retrieving submodule ref store
Looking up submodule ref stores has two deficiencies: - The initialized subrepo will be attributed to `the_repository`. - The submodule ref store will be tracked in a global map. This makes it impossible to have submodule ref stores for a repository other than `the_repository`. Modify the function to accept the parent repository as parameter and move the global map into `struct repository`. Like this it becomes possible to look up submodule ref stores for arbitrary repositories. Note that this also adds a new reference to `the_repository` in `resolve_gitlink_ref()`, which is part of the refs interfaces. This will get adjusted in the next patch.
