    socket: Implement SO_RERROR
    SO_RERROR indicates that receive buffer overflows should be handled as
    errors. Historically receive buffer overflows have been ignored and
    programs could not tell if they missed messages or messages had been
    truncated because of overflows. Since programs historically do not
    expect to get receive overflow errors, this behavior is not the
    This is really really important for programs that use route(4) to keep
    in sync with the system. If we loose a message then we need to reload
    the full system state, otherwise the behaviour from that point is
    undefined and can lead to chasing bogus bug reports.
