[PATCH v4 4/6] remote: remove the_repository->remote_state from static methods

[Glen Choo <chooglen@google.com>]

Replace all remaining references of the_repository->remote_state in
static functions with a struct remote_state parameter.

To do so, move read_config() calls to non-static functions and create a
family of static functions, "remotes_*", that behave like "repo_*", but
accept struct remote_state instead of struct repository. In the case
where a static function calls a non-static function, replace the
non-static function with its "remotes_*" equivalent.
