Andreas Fackler f7d4860a94 Fix DHB test: wait for lagging nodes. 
The Dynamic Honey Badger tests would currently fail _without_ faulty
nodes, because with "first" delivery, all but the first _N - f_ nodes
are lagging indefinitely.

This change makes sure we give lagging nodes a chance to finish the first
phase of the test and arrive at the batch containing the completed
`Remove` event.

Andreas Fackler e9b960d020 Fix and clean up the HoneyBadger impl. 
* Remove unnecessary recursive method calls.
* Add `handle_message` (without the trait).
* Fix a bug where `handle_message_content` would create an `EpochState`
  with the wrong number.

Andreas Fackler eeb519862f Simplify Honey Badger tests and example. 2018-08-01 18:52:32 +02:00
Andreas Fackler d19afc2634 Change the QHB criterion for moving on to the next epoch. 
`QueueingHoneyBadger` now waits after an output, and only makes its
proposal for the next epoch when:

* there are pending transactions in the queue,
* there are pending key generation or vote messages, or
* _f + 1_ other validators have already made their proposal.

This rule should work well for small networks: With 1 - 3 nodes, it will
produce a new batch whenever at least one of them has transactions to
contribute. In larger networks, it prevents an adversary controlling _f_
nodes from producing lots of empty epochs.

An exception is made for a currently joining validator: We will commit
up to _(N + 1)² + 1_ key generation messages for them, which is the
maximum number a correct node will send.
