Rework the "connect to backend logic".

Avoid calling getaddrinfo() for every connect by catching the result
in the backend structure.

Minimize number of socket/connect calls by caching the last good
address in the backend structure.

If all addresses in the cached getaddrinfo() result fails, call
getaddrinfo() again (to catch DNS changes) and try the list again.
