Well, process-send on a newly made make-network-connection :nowait t
will no longer fail, which is an API change.  :-)

The only thing missing is whether to have a new state for TLS
connections.  When you've asked for a TLS connection, all these commands
should block until TLS has been negotiated, too.  We can have the TLS
commands check for that explicitly (which makes the blocking :nowait
users happy), but we also need a way to tell the non-blocking :nowait
users that the connection is now ready for non-blocking usage.

We could just leave the connection in 'connecting state, perhaps...
