Entrypoint which only performs message validation

If a transaction contains n messages m_1 … m_n, then they MUST be processed as follows: validate(m_1), execute(m_1), …, validate(m_n), execute(m_n) That is, the state transition of message i must be applied before message i+1 is validated. This is equivalent to calling dispatch() on each successively.
