EIP158 Progress

[ayrat555]

• EIP155 Replay attack protection - prevents transactions from one Ethereum chain from being rebroadcasted on an alternative chain.
• EIP160 eip160 change byte cost for exp op #346 EXP cost increase - adjusts the price of EXP opcode so it balances the price of EXP with the computational complexity of the operation, essentially making it more difficult to slow down the network via computationally expensive contract operations
• EIP161 clean touched accounts EIP161 #359 consider beneficiary when cleaning touched accounts (EIP161) #360 add message call recipient to touched accounts (EIP161) #361 State trie clearing - makes it possible to remove a large number of empty accounts that were put in the state at very low cost as a result of earlier DoS attacks.
• EIP170 limit code size EIP170 #350 Contract code size limit - changes the maximum code size that a contract on the blockchain can have.
