Introducing proto-streamer

[John Pritchard]

This server should be good for a great many apps from chat to games
and more. Using tcp is good for fairly fast interactions, second only
to udp which is necessary at the most extreme as for voice. Using
http has the cost of requiring one stream in each direction, uplink &
downlink, but has the benefit of traversing firewalls and proxies
nicely.

With a tagged data format like protobuf, message overhead is a couple
bytes per field. Typically one byte for data type, and then a byte or
two (each seven bits) for payload length.

The proto-streamer does not yet have any application frameworks as for
sessions or stores. The first, for sessions, is currently in
progress.
