PROTON-1095: [C++ binding] Improve error handling with events
- Introduce on_unhandled_error that is called if the application does
  not handle the specific error conditions itself.
-- Default action of on_unhandled_erro is to raise an exception with a
   useful message.
- Added condition to represent error state (wrapper for pn_condition_t)
x Examples now don't seem robust enough and fail because of errors

> The C++ binding needs a disciplined and effective way to handle protocol (and 
> transport) errors.
> Currently the API has some error events, however if they are not handled the 
> program will just hang - it would be better in this case to throw an 
> exception so that the program doesn't just hang.
> Another issue is creating error states (attaching a condition) when closing a 
> connection/session/link - there should be some straightforward way to 
> indicate the error to your peer.
