hive: add ethereum/engine simulator
some test with multiple client still need polishing.
merge test using specially crafted blocks need to be added.

Redesign of BaseVMState descriptor (#923)
* Redesign of BaseVMState descriptor

why:
  BaseVMState provides an environment for executing transactions. The
  current descriptor also provides data that cannot generally be known
  within the execution environment, e.g. the total gasUsed which is
  available not before after all transactions have finished.

  Also, the BaseVMState constructor has been replaced by a constructor
  that does not need pre-initialised input of the account database.

also:
  Previous constructor and some fields are provided with a deprecated
  annotation (producing a lot of noise.)

* Replace legacy directives in production sources

* Replace legacy directives in unit test sources

* fix CI (missing premix update)

* Remove legacy directives

* chase CI problem

* rebased

* Re-introduce 'AccountsCache' constructor optimisation for 'BaseVmState' re-initialisation

why:
  Constructing a new 'AccountsCache' descriptor can be avoided sometimes
  when the current state root is properly positioned already. Such a
  feature existed already as the update function 'initStateDB()' for the
  'BaseChanDB' where the accounts cache was linked into this desctiptor.

  The function 'initStateDB()' was removed and re-implemented into the
  'BaseVmState' constructor without optimisation. The old version was of
  restricted use as a wrong accounts cache state would unconditionally
  throw an exception rather than conceptually ask for a remedy.

  The optimised 'BaseVmState' re-initialisation has been implemented for
  the 'persistBlocks()' function.

also:
  moved some test helpers to 'test/replay' folder

* Remove unused & undocumented fields from Chain descriptor

why:
  Reduces attack surface in general & improves reading the code.

move stateDB from VMState to chainDB
previously, every time the VMState was created, it will also create
new stateDB, and this action will nullify the advantages of cached accounts.

the new changes will conserve the accounts cache if the executed blocks
are contiguous. if not the stateDB need to be reinited.

this changes also allow rpcCallEvm and rpcEstimateGas executed properly
using current stateDB instead of creating new one each time they are called.

Fearture/poa clique tuning (#765)
* Provide API

details:
  API is bundled via clique.nim.

* Set extraValidation as default for PoA chains

why:
  This triggers consensus verification and an update of the list
  of authorised signers. These signers are integral part of the
  PoA block chain.

todo:
  Option argument to control validation for the nimbus binary.

* Fix snapshot state block number

why:
  Using sub-sequence here, so the len() function was wrong.

* Optional start where block verification begins

why:
  Can speed up time building loading initial parts of block chain. For
  PoA, this allows to prove & test that authorised signers can be
  (correctly) calculated starting at any point on the block chain.

todo:
  On Goerli around blocks #193537..#197568, processing time increases
  disproportionally -- needs to be understand

* For Clique test, get old grouping back (7 transactions per log entry)

why:
  Forgot to change back after troubleshooting

* Fix field/function/module-name misunderstanding

why:
  Make compilation work

* Use eth_types.blockHash() rather than utils.hash() in Clique modules

why:
  Prefer lib module

* Dissolve snapshot_misc.nim

details:
  .. into clique_verify.nim (the other source file clique_unused.nim
  is inactive)

* Hide unused AsyncLock in Clique descriptor

details:
  Unused here but was part of the Go reference implementation

* Remove fakeDiff flag from Clique descriptor

details:
  This flag was a kludge in the Go reference implementation used for the
  canonical tests. The tests have been adapted so there is no need for
  the fakeDiff flag and its implementation.

* Not observing minimum distance from epoch sync point

why:
  For compiling PoA state, the go implementation will walk back to the
  epoch header with at least 90000 blocks apart from the current header
  in the absence of other synchronisation points.

  Here just the nearest epoch header is used. The assumption is that all
  the checkpoints before have been vetted already regardless of the
  current branch.

details:
  The behaviour of using the nearest vs the minimum distance epoch is
  controlled by a flag and can be changed at run time.

* Analysing processing time (patch adds some debugging/visualisation support)

why:
  At the first half million blocks of the Goerli replay, blocks on the
  interval #194854..#196224 take exceptionally long to process, but not
  due to PoA processing.

details:
  It turns out that much time is spent in p2p/excecutor.processBlock()
  where the elapsed transaction execution time is significantly greater
  for many of these blocks.

  Between the 1371 blocks #194854..#196224 there are 223 blocks with more
  than 1/2 seconds execution time whereas there are only 4 such blocks
  before and 13 such after this range up to #504192.

* fix debugging symbol in clique_desc (causes CI failing)

* Fixing canonical reference tests

why:
  Two errors were introduced earlier but ovelooked:
   1. "Remove fakeDiff flag .." patch was incomplete
   2. "Not observing minimum distance .." introduced problem w/tests 23/24

details:
  Fixing 2. needed to revert the behaviour by setting the
  applySnapsMinBacklog flag for the Clique descriptor. Also a new
  test was added to lock the new behaviour.

* Remove cruft

why:
  Clique/PoA processing was intended to take place somewhere in
  executor/process_block.processBlock() but was decided later to run
  from chain/persist_block.persistBlock() instead.

* Update API comment

* ditto

Feature/goerli replay clique poa (#743)
* extract unused clique/mining support into separate file

why:
  mining is currently unsupported by nimbus

* Replay first 51840 transactions from Goerli block chain

why:
  Currently Goerli is loaded but the block headers are not verified.
  Replaying allows real data PoA development.

details:
  Simple stupid gzipped dump/undump layer for debugging based on
  the zlib module (no nim-faststream support.)

  This is a replay running against p2p/chain.persistBlocks() where
  the data were captured from.

* prepare stubs for PoA engine

* split executor source into sup-modules

why:
  make room for updates, clique integration should go into
  executor/update_poastate.nim

* Simplify p2p/executor.processBlock() function prototype

why:
  vmState argument always wraps basicChainDB

* split processBlock() into sub-functions

why:
  isolate the part where it will support clique/poa

* provided additional processTransaction() function prototype without _fork_ argument

why:
  with the exception of some tests, the _fork_ argument is always derived
  from the other prototype argument _vmState_

details:
  similar situation with makeReceipt()

* provide new processBlock() version explicitly supporting PoA

details:
  The new processBlock() version supporting PoA is the general one also
  supporting non-PoA networks, it needs an additional _Clique_ descriptor
  function argument for PoA state (if any.)
  The old processBlock() function without the _Clique_ descriptor argument
  retorns an error on PoA networgs (e.g. Goerli.)

* re-implemented Clique descriptor as _ref object_

why:
  gives more flexibility when moving around the descriptor object

details:
  also cleaned up a bit the clique sources

* comments for clarifying handling of Clique/PoA state descriptor

drop PublicNetwork enum usage and replace it with NetworkId
we cannot limit the `--networkid` switch to values available in
`PublicNetwork` enum. it should able to accept very wide range of

fixes `getRecipient`: using `sender` param instead of calculating sender itself
usually, there is always a sender around `getRecipient` call.
no need to recalculate sender. and more important, in some of
JSON-RPC/GraphQL call, the sender is come from `rpcCallData`,
not from `tx.getSender`. or in ohter situation when the tx is
an unsigned tx, without `r,s,v` fields to calculate sender.
