remote: use remote_state parameter internally

Browse Source 
Without changing external-facing functions, replace
the_repository->remote_state internally by adding a struct remote_state
parameter.

As a result, external-facing functions are still tied to the_repository,
but most static functions no longer reference
the_repository->remote_state. The exceptions are those that are used in
a way that depends on external-facing functions e.g. the callbacks to
remote_get_1().
