* [PAN-2946] - changes in core JSON-RPC method to support ReTestEth
Some of the methods need to have a changeable reference to stuff like
blockchainqueries. For the impacted methods the solution is to wrap them
in a Supplier<> interface. This includes new constructors for re-used methods.
Also include the debug_accountRangeAt method as it's namespaced as debug.
Some features needed for retesteth are flag controlled to preserve current behaviors.

Retesteth requires support for mining without block rewards and without PoW.
No Proof simply requires exposing the nonce generator and using a special
EthHashSolver.
No Reward is supported via a flag in the ProtocolSpec, stating whether or not
to skip zero rewards. For frontier, homestead, and tangerine whistle (EIP150)
this flag is false. For all other forks and all other consensus engines the
flag is true, even when emulating EVM state from those three forks as all
non-PoW consensus engines never consider block rewards.

This reverts commit 814b36e4
The needed chantes to get rid of Instant.now (which is also needed to get rid
of the wall clock dependency) are too deep and intrusive into IBFT to try and
speed patch them in that some APIs require re-work, so in the interst of test
stability this gets sheleved until it is all ready.

To allow us to reset the timestamp in the blockchain for Retesteth support
we need to pass a Clock to affected APIs and use that instead of the static method
System.currentTimeMillis(). The most consistent way to do this that will ensure
that the API does not sneak back in is to ban the method via ErrorProne.
TestClock.fixed() was altered to return the "now" time of the first time the fixed clock was requested, needed for many header validation tasks validating headers are not from the future.

* Don't copy collections if we don't need to. Change types higher up if needed.
* Don't use Guava's Object.equal, use Java's Objects.equals.
** add errorprone test to enforce the banning of Guava's Objects class.

Moves init code into a separate builder instead of a static init method, with common code in an abstract base class and subclasses of the builder for each of the consensus variants.

Move RocksDBStats to it's own module. This also brings metrics to
metrics:core since none of our other module have nested modules but
they have peer modules.

* [PRIV-41] Use metrics system for private state db
- Use PrivacyParametersBuilder to build PrivacyParameters
- refactor PrivacyParameters to expose default options
- refactor test builders to use PrivacyParameters.DEFAULT
- Use URI in Enclave
* Fix: enclave tests from bad merge
* Fix privacy acceptance tests after db configuration changes
* Switch to use nested class for PrivacyParametersBuilder

* Added ability to subscribe to dropped transactions from the transaction pending pool.
Implemented subscription webservice to support this.
* Added metrics to the pending transactions, tracking the number of local and remote transactions in the pool.
* Converted listener management in pending transactions to use the Subscribers util object.

Biggest change is that UnusedVariable and UnusedMethod went to WARN by
default. Since our build is a no warning build this means we either need
to turn them off or fix them. I mostly opted for the latter. Test code
was mostly fixed, unused loggers were deleted, and other shipped code
was mostly suppressed.
Two less noisy fixes to not use `SortedSet` and to use zero based
comparable results instead of -1, 0, and 1. Also a compiler nit in
errorprone was suppressed, per the description it won't affect us.

* Store the instant that a pending transaction is added to the txpool, and expose this out through the api.
* Clock.systemUTC only used once.
* TestClock class added with a factory method for a fixed clock.

Adds a PeerValidator that, when the Dao fork milestone is in use, checks that the Dao block is present on each peer when they connect and disconnects them if they are on the wrong chain.
Also:
* Make GetHeadersFromPeer task stricter in validating response matches.
* Update BlockHeadersMessage to return a list of headers
* Add more controls to DeterministicEthScheduler test util

There is a failure mode of IBFT whereby a validator fails to import
a block, and also fails to receive the NewBlock message from its
peers. This means said validator is unable to participate in
subsequent rounds, and may cause the network to halt.
To overcome this issue, if an IBFT validator receives messages from
a future height, it will update the "BestEstimatedHeight" of the
corresponding EthPeer object, such that the Synchroniser will
(eventually) download the requisite blocks - thus allowing the
IBFT network to continue to operate.

It was identified during a demonstration that Pantheon, when running
in IBFT would show a "Bad Block Import" when a validator was added or
removed from the validator pool.
It was determined this was due to IBFT maintaining a single, 'global'
copy of the curent list of validators, which was updated when a block
was imported - thus when a block which had been imported vi IBFT
was then received via Eth block propogation, the validator list would
not align with the global list (as it had been updated in the IBFT
import).
The solution has been to utilise the VoteTallyCache as used in the
Clique implementation.

With upcoming changes to remove the NewRound message, and place
the RoundChangeCertificate in the Proposal, it was decided to break
out the RoundChangeCertiifcate validation into a separate file
to minimise changes during message restructuring.

This change moves blocks out from the signed portion of the IBFT messages (Proposal, RoundChange and NewRound).
This has grossly affected the message validators and message factories - but otherwise does not affect the general behaviour of the system (other than reducing message size of the NewRound messages).

Two changes:
* Stream chains now take up less vertical lines, only breaking on
stream operations.
* Long annotations that span multiple lines no longer have a dangling
parentesis and indent 4 spaces.
