klippy: Support generic printer_state() and stats() callbacks

Browse source 
Instead of hardcoding which objects are called on state transitions,
allow any "printer object" to be invoked if it has a printer_state()
method.  Convert connect, ready, shutdown, and disconnect callbacks to
this mechanism.

Similarly, allow all printer objects to provide a stats() callback.
