Test case for 0848814ac49616

"I'm not sure if you'll like my use of the limited broadcast address
  for simulating an ENETUNREACH error with a TCP connection, but it's
  the best that I could think of.  Basically, we want to trigger a
  non-EINPROGRESS error in evutil_socket_connect() immediately at the
  connect() in order to bring about the assertion in the
  evhttp_connection_fail() error handling code."
