Pre functional snap to full sync (#1546)
* Update sync scheduler pool mode

why:
  The pool mode allows to loop over active peers one after another. This
  is ideal for soft re-starting peers. As this is a two tier experience
  (start/stop, setup/release) the loop must be run twice. This is
  controlled by a more rigid re-definition of how to use the `poolMode`
  flag.

* Mitigate RLP serialiser deficiency

why:
  Currently, serialising the `BlockBody` in not conevrtible and need
  to be checked in the `eth` module. Currently a local fix for the
  wire protocol applies. Unit tests will stay (after this local solution
  will have been removed.)

* Code cosmetics and massage

details:
  Main part is `types.toStr()` as a unified function for logging block
  numbers.

* Allow to use a logical genesis replacement (start of history)

why:
  Snap sync will set up an arbitrary pivot at a block number different
  from zero. In fact, the higher the block number the better.

details:
  A non-genesis start of history will currently only affect the score
  values which were derived from the difficulty.

* Provide function to store the snap pivot block header in chain db

why:
  Together with the start of history facility, this allows to proceed
  with full syncing once snap has finished.

details:
  Snap db storage was switched from a sub-tables to the flat chain db.

* Provide database completeness and sanity checker

details:
  For debugging on smaller databases, only

* Implement snap -> full sync switch

mark the new chain as canonical when calling db.setHead
the new chain marked as canonical is from the new head down to
forking point. most of the time, the forking point is the parent

Zahary Karadjov 137eb97766 Initial implementation of the merge spec
Includes a simple test harness for the merge interop M1 milestone

This aims to enable connecting nimbus-eth2 to nimbus-eth1 within
the testing protocol described here:

https://github.com/status-im/nimbus-eth2/blob/amphora-merge-interop/docs/interop_merge.md

To execute the work-in-progress test, please run:

In terminal 1:

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  Also, the BaseVMState constructor has been replaced by a constructor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.

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
custom NetworkId.

fixes crappy custom genesis and chain config parser
instead of using stdlib/json, now we switch to json_serialization
the result is much tidier code and more robust when parsing
optional fields.

fixes getReceipts proc signature in db_chain.nim
instead of using header as input param, now getReceipts using
receiptRoot hash, the intention is clearer and less data passed around
when we only using receiptRoot instead of whole block header.
