Right.  We shouldn't necessarily expect the server to start and then decide
whether it is a code model server or debug server when the client connects
and tells it.  Currently the model is that the client is responsible for
starting the server and then connecting to it.  We just need a different
command-line option for a debug client to start a debug server instead.

The reason for the separate bounding structure is so that the entire message
can be extracted from a stream without having to run a live JSON parser on
it.  We can extract the whole message and then parse it as JSON.  Another
reason is that the --debug mode puts the messaging straight on stdout/stdin
that are also used for other output that does not conform to the protocol.
The separate bracketing is then necessary.

Please re-open the original MR.  I think high-level discussion on this
list has established that your approach is viable.  It may take me a while
to find time for a thorough review though.

Thanks,
