        src/external/bsd/dhcpcd/dist/src: dhcp.c dhcp6.c if-bsd.c ipv6nd.c
        src/lib/libc/sys: getsockopt.2
        src/share/man/man7: sysctl.7
        src/sys/kern: uipc_socket.c uipc_socket2.c
        src/sys/sys: socket.h

Log Message:
- Introduce a new SO_RERROR socket option to explicitly turn on
  receive overflow errors re-instating the default behavior to
  silently ignore them as before 2018-03-19.
- Introduce a new kern.sooptions sysctl to control the default
  behavior of socket options. Setting this to 0x4000 (SO_RERROR),
  turns on receive overflow error reporting for all sockets.
- Change dhcpcd to turn on SO_RERROR on all its sockets.

As discussed in tech-net.
