Re: [PATCH 02/13] submodule--helper: get remote names from any repository

`get_default_remote()` retrieves the name of a remote by resolving the

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.

I'd find this easier to follow if this were just squashed into the next
commit. Both are rather small, but following the context of first adding
a function, then using it, instead of just adding it, changing the old
users etc. is harder than just having it in one commit.
