SO_ACCEPTCONN in getsockopt

Hi

POSIX-compliant getsockopt should have possibility to
obtain SO_ACCEPTCONN flag value from so_options. See
http://www.opengroup.org/onlinepubs/007904975/functions/getsockopt.html
But FreeBSD getopt doesn't have this possibility.

I think that commiters can add one line
to sys/kern/uipc_socket.c (to sogetopt function)
to provide that functionality.
It can be something like this:
====
~  case SO_USELOOPBACK:
~  case SO_DONTROUTE:
~  case SO_DEBUG:
~  case SO_KEEPALIVE:
~  case SO_REUSEADDR:
~  case SO_REUSEPORT:
~  case SO_BROADCAST:
~  case SO_OOBINLINE:
+ case SO_ACCEPTCONN:
~  case SO_TIMESTAMP:
~     optval = so->so_options & sopt->sopt_name;
~        integer:
~     error = sooptcopyout(sopt, &optval, sizeof optval);
~                                ====


PS. Is there any other way to obtain this value from
kernel to userspace? May be ioctl?
