Extends all APIs so that the user doesn't need to import the
`DistAlgorithm` trait.
Also, removes the error on inputting too late into `BinaryAgreement`:
whether the input still matters is an implementation detail.
The `network` test module now verifies that correct nodes are never
reported as faulty.
The `DuplicateAck` fault is removed for now, because the same ack is
usually handled multiple times in DHB.
Instead of just the public key, the batches returned from
`DynamicHoneyBadger` and `QueueingHoneyBadger` now contain the full
`NetworkInfo`, so the user can use the validators' keys for signing and
encryption.
Using `hbbft` in other software that is based on frameworks like [tokio](https://tokio.rs), being `Send` is often a requirement on shared data structures.
* Add support for RNG instantiation in proptests.
* Use `proptest` module strategy to create the rng for `net_dynamic_honey_badger`.
* Use seed generation instead of RNG instantiation in tests.
* Remove fixed RNG in `generate_map`.
* `VirtualNet` now supports setting the random generator through the builder.
* Add missing `time_limit` field to `::std::fmt::Debug` trait implementation on `NetBuilder`.
* Pass an instantiated random number generator through `NewNodeInfo` as a convenience.
* Make the random number generator of `DynamicHoneyBadgerBuilder` configurable, at the cost of now requiring mutability to call `build_first_node()`.
* Ensure RNGs are derive from passed in seed in `net_dynamic_hb` tests.
* Correct inappropriate use of `random::Random` instead of `Rng::gen` to generate dependent values in `binary_agreement`.
The original implementation used `rand::random()`, which will always use the `thread_rng`, ignoring the fact that an RNG has actually been passed in.
* Do not use `OsRng` but passed in RNG instead.
* Use reference/non-reference passing of rngs more in line with the `rand` crates conventions.
* Document `rng` field on `DynamicHoneyBadger`.
* Make `SyncKeyGen` work with the extend (`encrypt_with_rng`) API of `threshold_crypto`.
* Use passed-in random number generator in `HoneyBadger`.
* Create `SubRng` crate in new `util` module to replace `create_rng()`.
* Use an RNG seeded from the configure RNG when reinitializing `DynamicHoneyBadger`.
* Use the correct branch of `threshold_crypto` with support for passing RNGs.
* spam protection part 1: remote epoch tracking in HoneyBadger
* moved handling of EpochStarted out of EpochState
* allowed EpochStarted from observers
* removed an unnecessary function call
* updated formatting to beta
* removed an unnecessary variable
* Move `CoinState` and `Agreement` definitions from `agreement/mod.rs`
to `.../agreement.rs`.
* Move `DynamicHoneyBadger` definition from `dynamic_honey_badger/mod.rs`
to `.../dynamic_honey_badger.rs`.
