Currently, if the server or the client fails to read some fields on a packet, it restore former values or set them to zero. The packet can be very different of what the other instance wanted to send. Actually this should never happen as long as the packets are encoded by the dio_put_xxx() functions and the capability string handle correctly the variants.

This patch break the connections when fields are missing or incorrectly encoded.
