The IBFT RoundState is responsible for determining if sufficient
valid messages have been received to deem the node "Prepared" or
"Committed".
Signed-off-by: Adrian Sutton <adrian.sutton@consensys.net>
Received New Round messages require significant validation to ensure their content is consistent and valid with regard the current state of the system.
This commit includes a class (and tests) which ensures illegally constructed NewRound messages are identified.
This does not include the action to be taken upon detection of an illegal New Round message.

The classes used around the IBFT Messaging classes have all been renamed to make their use less cumbersome throughout the codebase.
Other issues are yet to be found (not all variable names and function names have been captured in this sweep).

A problem was identified whereby the vote in a child block was applied to the parent, this was resolved by
duplicating the parent VoteTally before modifying it, and injecting to the child block.
Some refactoring was also conducted to make VoteTally logic simpler.

Reverts #339
Görli's testnet regularly has proposers miss their turn and their
genesis block actually had a bad validator specified (that was voted out
as soon as they could) So many blocks do not have the proper "proposer"
as their block generator. As a consequence the
CliqueDifficultyValidationRule fails regularly, in fact it fails at
block 3, so this should be easy to re-create locally.

Clique Proposer Selection would choose an incorrect peer
when a signer was removed from the pool, as the algorithm worked
purely on the block count.
The algorithm has now been updated to ensure the next proposer is
incrementally the next signer in the ordered list, based on the
parent's proposer

Upgrade dependency versions
* All version information is merged into one place
* Upgrade most version to their latest non-test version.
* dependencies are now sorted
Two dependencies were not upgraded:
errorprone - There are new checks that require build or source changes.
vertex - The license to eclipse 2.0 which is not in our current approved license list.
The change is trivial but for tracability it should be done alone.

The ProposerSelection logic has been reworked such that it now accepts
a BlockInterface, through which IBFT parameters can be accessed
directly from the block header, without requiring literal hashing etc.
This has required the VoteBlockInterface to be renamed to
BlockInterface.

Clique was using integer arithmetic to calculate how much "wiggle"
delay should be added when the proposer is "out of turn".
This would mean when an odd number of validators was in use, the
max delay would be 250ms less than the expected value.

IBFT requires various aspects of the mining infrastructure in order
to create a proposed block.
This includes specifically the BlockCreator and MiningCoordinating,
the mining executor is not required at this stage, nor is the miner.

* Remove release/retain requirement from MessageData.
MessageData now wraps a BytesValue rather than a Netty ByteBuf so we no longer need to call release/retain and pass that through to the underlying ByteBuf.
Entirely removed support for a BytesValue wrapping a Netty ByteBuf as it does not provide any way to release the underlying ByteBuf.
* Add BytesValue.copyTo(byte[]) to avoid the need to call getArrayUnsafe() to copy the data.

The consensus-mechanism specific block values have been separated
from the VoteTallyUpdater such that there is a single updater rather
than one per consensus mechanism.
This has necessitated the creation of a custom serialiser/
deserialiser for each mechanism instead.
This change will ultimatley bleed through to the proposed votes and
their insertion to mined blocks.

The Ibft consensus mechanism is responsible for sending a variety of
messages to other validating nodes in the network (provided they have
a point-to-point connection to them).
This change tracks which nodes have connected to the IBFT
subprotocol, and provides the functionality to only transmit messages
to nodes which are also validators.
