Due to #134201 I've re-opened this, my patch was wrong.

UDP sockets can be connected, and on some systems, calling send() with a TO address will fail.

UDP sockets can even be connected to a new address while connected or disconnected by trying to connect to a AF_UNSPEC address.

I'm going to re-work this.
