EIP-1559: Fee market change for ETH 1.0 chain Transaction and BlockHeader already updated in nim-eth repo to support EIP-1559 EIP-1559 header validation and gasLimit validation already implemented in previous commit This commit deals with block validation: - Effective gasPrice per EIP-1559 - new miner reward based on priorityFee

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 Also, the BaseVMState constructor has been replaced by a constructor that does not need pre-initialised input of the account database.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