UDPServer handles PacketPeerUDP-client association

UDPServer now uses a single socket which is shared with the
PacketPeerUDP it creates and has a new `poll` function to read incoming
packets on that socket and delivers them to the appropriate peer.
PacketPeerUDP created this way never reads from the socket, but are
allowed to write on it using sendto.

This is needed because Windows (unlike Linux/BSD) does not support
packet routing when multiple sockets are bound on the same address/port.
