Jason A. Donenfeld d6b3bc6948 wg: use stream instead of seqpacket
To support OS X and Windows, we have to. Ugh.

Jason A. Donenfeld a773a23c75 wg: abstract sockets are dangerous
They have no permissions, so we're probably better off just creating a
socket file with the umask set, as we do in BSD.

Jason A. Donenfeld b16641e30c wg: first additions of userspace integration
This is designed to work with a server that follows this:

  struct sockaddr_un addr = {
      .sun_family = AF_UNIX,
      .sun_path = "/var/run/wireguard/wguserspace0.sock"
  };
  int fd, ret;
  ssize_t len;
  socklen_t socklen;
  struct wgdevice *device;

  fd = socket(AF_UNIX, SOCK_DGRAM, 0);
  if (fd < 0)
      exit(1);
  if (bind(fd, (struct sockaddr *)&addr, sizeof(addr)) < 0)
      exit(1);

  for (;;) {
      /* First we look at how big the next message is, so we know how much to
       * allocate. Note on BSD you can instead use ioctl(fd, FIONREAD, &len). */
      len = recv(fd, NULL, 0, MSG_PEEK | MSG_TRUNC);
      if (len < 0) {
          handle_error();
          continue;
      }
      /* Next we allocate a buffer for the received data. */
      device = NULL;
      if (len) {
          device = malloc(len);
          if (!device) {
              handle_error();
              continue;
          }
      }
      /* Finally we receive the data, storing too the return address. */
      socklen = sizeof(addr);
      len = recvfrom(fd, device, len, 0, (struct sockaddr *)&addr, (socklen_t *)&socklen);
      if (len < 0) {
          handle_error();
          free(device);
          continue;
      }
      if (!len) { /* If len is zero, it's a "get" request, so we send our device back. */
          device = get_current_wireguard_device(&len);
          sendto(fd, device, len, 0, (struct sockaddr *)&addr, socklen);
      } else { /* Otherwise, we just received a wgdevice, so we should "set" and send back the return status. */
          ret = set_current_wireguard_device(device);
          sendto(fd, &ret, sizeof(ret), 0, (struct sockaddr *)&addr, socklen);
          free(device);
      }
  }

Jason A. Donenfeld 1a64438b21 contrib: remove extraneous cruft
We don't want people packaging these or even using these scripts, which
are only useful for limited development circumstances, so get rid of
them. More widespread development testing techniques still exist in
src/debug.mk and src/netns.sh
