Title: Handoff Manager now in charge of senders and receivers.

* Vnode and Listener go through the handoff manager to spawn senders and receivers.
* Handoff manager uses handoff_concurrency to determine if a new sender or receiver can spawn.
* Handoff lock has been removed. Just die and let vnode or listener try again.
* Ability to hard-kill handoffs.
* Handoffs have (unused) status information and know when they were started to track time.
