perror and fprintf can be removed because all clients can now consume Errors properly. However, we'll need to change the non-blocking connect handlers to take an Error, in order to improve error handling for migration with the TCP protocol.
This is a minor degradation in error reporting for outgoing migration. However, until 1.2 this case just failed without even attempting to connect, so it is still an improvement as far as overall QoI is concerned.
