* eip1559 hard fork activation * eip1559 hard fork activation 2 * added new transaction type for eip1559 * added base fee field to block header * fmt fix * added base fee calculation. added block header validation against base fee * fmt * temporarily added modified transaction pool * tx pool fix of PendingIterator * tx pool fix of UnorderedIterator * tx pool added test for set_scoring * transaction pool changes * added tests for eip1559 transaction and eip1559 receipt * added test for eip1559 transaction execution * block gas limit / block gas target handling * base fee verification moved out of engine * calculate_base_fee moved to EthereumMachine * handling of base_fee_per_gas as part of seal * handling of base_fee_per_gas changed. Different encoding/decoding of block header * eip1559 transaction execution - gas price handling * eip1559 transaction execution - verification, fee burning * effectiveGasPrice removed from the receipt payload (specs) * added support for 1559 txs in tx pool verification * added Aleut test network configuration * effective_tip_scaled replaced by typed_gas_price * eip 3198 - Basefee opcode * rpc - updated structs Block and Header * rpc changes for 1559 * variable renaming according to spec * - typed_gas_price renamed to effective_gas_price - elasticity_multiplier definition moved to update_schedule() * calculate_base_fee simplified * Evm environment context temporary fix for gas limit * fmt fix * fixed fake_sign::sign_call * temporary fix for GASLIMIT opcode to provide gas_target actually * gas_target removed from block header according to spec change: https://github.com/ethereum/EIPs/pull/3566 * tx pool verification fix * env_info base fee changed to Option * fmt fix * pretty format * updated ethereum tests * cache_pending refresh on each update of score * code review fixes * fmt fix * code review fix - changed handling of eip1559_base_fee_max_change_denominator * code review fix - modification.gas_price * Skip gas_limit_bump for Aura * gas_limit calculation changed to target ceil * gas_limit calculation will target ceil on 1559 activation block * transaction verification updated according spec: https://github.com/ethereum/EIPs/pull/3594 * updated json tests * ethereum json tests fix for base_fee
