Dispatch read one byte of the code, so a code with a non-zero high byte was handled as its low byte. Message::get_message_code now reads the whole little-endian uint32 and handlers register by u32. PeerInit and PierceFirewall, the only frames with a one-byte code, get their own accessor for the listener's first frame.
