Roy Marples f452713408 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 default. 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.
