A net.UDPListener is the datagram equivalent of a net.Conn. This patch
accepts at most one connection from vsock and attempts to read and write
UDP datagrams along it.

This represents what is needed from the frontend side of the proxy:
- the ability to receive a UDP datagram and know who it is from
- the ability to send a UDP datagram to a particular destination
- the ability to close
