If a port is unbound, trying to call its peer will likely cause a segfault. Rather than check if a port is bound every time you go to use it, we can instead bind to a default peer which just throws an exception back to the caller. The caller can catch the exception and report the error. This change adds a common new class to throw as the exception, and also a small utility function which reports the error and dies.
