The protocol so far was client->server only. That is, there was no
sane way for a client to check whether a plugin on the server (service)
was available or not. E.g. calling Client::setEnabled(true) 'succeeded',
without a check whether there is actually a service to talk to.
The new protocol replaces this shortcoming by a service discovery
mechanism: Both client & service announce their available plugins at
handshake time, and later on if there are changes. The status is
reflected in Client::status() and Service::Status() , which are either
NotConnected - no network connection, or not registered properly
Unavailable - TCP/IP connection works, but no plugin with the same
name on the other side
Enabled - You can connect to plugin on other side
The status changes happen automatically (no setEnabled() anymore).
Furthermore a version ID was added to the handshake, so that we can
extend the protocol further in the future :)
