Add fanout mode PACKET_FANOUT_CBPF that accepts a classic BPF program to select a socket. This avoids having to keep adding special case fanout modes. One example use case is application layer load balancing. The QUIC protocol, for instance, encodes a connection ID in UDP payload. Also add socket option SOL_PACKET/PACKET_FANOUT_DATA that updates data associated with the socket group. Fanout mode PACKET_FANOUT_CBPF is the only user so far.
