wireproto: explicitly track which requests are active

We previously only tracked which requests are receiving. A
misbehaving client could accidentally have multiple requests with
the same ID in flight.

We now explicitly track which request IDs are currently active.
We make it illegal to receive a frame associated with a request
ID that has already been dispatched.
