During the transition from contract mode to block header mode, when creating the extra data for a new block, we need to look ahead to the next block's voteProvider to obtain the nonEmpty one associated with the BlockValidatorProvider.
This only applies to ForkingValidatorProvider which is currently only used for QBFT. However, we don't want QBFT to know it's using a ForkingValidatorProvider. Therefore we need to implement getVoteProviderAfterBlock on the ValidatorProvider interface even though it's implementation is equivalent to getVoteProvider.

* Only allow new rpc endpoints to be defined

Broad reaching optimizations to speed up EVM calculations
* Generally speaking, use int and long where it is more appropriate than UInt256 (memory indexes mostly)
* Move the internal stack to Bytes from UInt256
* Re-work the flow of many operations to account for the above

Move EVM to a standalone module
Move the EVM classes to a standalone module. This is mostly moves but
some API re-resign to peel out some features not essential to the EVM,
such as privacy support and ties to the data storage subsystem.

* Create new datatypes module
Create a new `datatypes` module to hold datatypes that are broadly used.
This will aid modularization by making sure the base types in the module
minimize the amount of unrelated support classes needed.

The Hash of a qbft payload is calculated by hashing the RLP'd bytes of the message-id, followed by the payload's encoded bytes.
RLP(msgCode, RLP(payload.encodedBytes()))

We were creating new in-memory storage segments each time we were
supposed to be retrieving it which prevented me from being able to test
what keys ended up being stored in that segment.

QBFT no longer validates all fields of the block header (eg nonce mixhash), as these have no bearing on the
safety model of the protocol.

When validating a RoundChange message, its important that not only
are there sufficient Prepare msgs in the PreparedCertificate, but
also that each are from a different validator (i.e. cannot simply
count the number msgs, but must count distinct authors).

Since the EIP-1559 transition is going away, simply use a set of
accepted transactions for transaction validator that we'll check
against.
Don't assume that there are two transaction types and instead check
what type the transactions are.
Use guessType when we're deserializing from json.

This is a stronger check than in the past, which potentially allowed for a the IBFT system to handle messages for the current round, even if a block had already been imported (but had not yet received the new-block event) - which in turn, could lead to a network fork in a adversarial environment.

For every block produced and imported directly log the same information
we would get from other import paths.
* If this node produced the block, note that with "Produced" instead of
"Imported"
* Log the size of the pending transaction pool
* Only log IBFT rounds at INFO if they go past round 0, DEBUG otherwise.
