RCX Message API
===============
unsigned char get_msg(); // wait for any message
void clear_msg(); // set message buffer to 0 (invalid message)
int send_msg(unsigned char msg); // send single byte msg, return 0 on success
wait_event(msg_received, msg); // msg=0, wait for any message,
// msg=1-255, wait for specific msg
extern unsigned char lnp_rcx_message; // contains last message received or 0 if none
