Merge pull request #184 from c0gent/c0gent-mod-reorg 
Reorganize `dynamic_honey_badger` and `agreement` modules slightly.

* Some additional rustfmt-ing crept in due to me accidentally using a newer version.

Reorganize `dynamic_honey_badger` and `agreement` modules slightly. 
* Move `CoinState` and `Agreement` definitions from `agreement/mod.rs`
  to `.../agreement.rs`.

  to `.../dynamic_honey_badger.rs`.

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.

Andreas Fackler 3b65f0cead Fix agreement bugs, and refactor a few fields. 
* Don't drop `Term` messages from previous epochs. They are still
  relevant for all future epochs.
* Restructure some fields to avoid unnecessary iteration and counting.
* Simplify the fields related to the common coin.
* Reorder the methods, so that the message handlers are all in one
  place.
* Handle the case where the coin value arrives before the required
  number of `Conf` messages.

Andreas Fackler 4bff2849f9 Fix bin_values change handling in agreement. 
* Call `on_bin_values_changed` even if there is only one value.
* Handle the case _f = 0_ correctly: `count_bval` can be equal to both
  _f + 1_ and _2 f + 1_.
