Add endpoint tracking to the stack.
In the future this will replace DanglingEndpoints. DanglingEndpoints must be
kept for now due to issues with save/restore.
This is arguably a cleaner design and allows the stack to know which transport
endpoints might still be using its link endpoints.
Updates #837
