replace random nonces with message sequence numbers in tcp crypto
...
Since TCP is reliable, we do not need to transmit the nonce itself;
the recipient can simply construct the nonce from its own message
counter. Hence there is no message envelope and we can thus remove a
whole layer of encoding.

Don't pass the sender UDPAddr through the crypto layer
...
The crypto layer doesn't need it, and the cost of an additional
closure allocation for each incoming UDP packet is modest.
Also, make the FrameConsumer the last parameter to IterateFrames.
It seems a more natural ordering.
