Stream protocol using sequence numbers

ie so they're more like TCP, for performance reasons.

Multiple acknowledgements in one packet would also be good. Needs more thought.

So here's what I'm thinking:

Upon arbitrary node A making a connection to arbitrary node B:

• openstream (see protocol-5.md) would include a second line, with supported protocols.
• The protocol specified in protocol-5.md would be mandatory, as a fall-back
• Node B could then specify which protocol will be used for communication, out of the list node A provided, in its response to the openstream message.
• Both nodes would then communicate using node B's preferred protocol, including the closing of streams and such.

Another option is to specify a simple protocol allowing node A to ask node B which stream protocols it supports, and then negotiating based on which one node A prefers. This could be done using reliable packets, and if it takes more than the time it takes for the acknowledgement to arrive again, give up on negotiating and fall back to the standard one.
