Thus in order to use it for retrieving the remote name of a submodule, we have to start a new subprocess which runs from the submodule directory. Let's instead introduce a function called `repo_get_default_remote()` which takes any repository object and retrieves the remote accordingly. `get_default_remote()` is then defined as a call to `repo_get_default_remote()` with 'the_repository' passed to it. Now that we have `repo_get_default_remote()`, we no longer have to start a subprocess that called `submodule--helper get-default-remote` from within the submodule directory. So let's make a function called `get_default_remote_submodule()` which takes a submodule path, and returns the default remote for that submodule, all within the same process. We can now use this function to save an unnecessary subprocess spawn in `sync_submodule()`, and also in a subsequent patch, which will require this functionality.
