[PATCH 03/13] transport-helper: factor out push_update_refs_status

[Sverre Rabbelier <srabbelier@gmail.com>]

The update ref status part of push is useful for the export command
as well, factor it out into it's own function.
---

  I didn't move the new function up above push_refs_with_push so that
  it is obvious to the reviewer that the change is trivial.
