blockchain: witness hash for BlockTx and revamped state machine logic #408

This patch introduces a BlockTx type: that encapsulates Tx with its utxo proofs. The block header commits to that object, making all the proofs and signatures authenticated by the block header, eliminating DoS vector during block processing. Also the blockchain state and mempool are simplified.
