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.
