Add a bit more theory around SSE transport shutdown, and some
documentation of the SSE transport protocol itself. Additionally, remove
a TODO to avoid the use of channel buffering for message queues in http
transports; instead, always write to message buffers in a select
statement containing a read from the done channel. The bounded size of
message buffers then serves to create backpressure for an overloaded
server.
