Adding family slot to socket addresses.
A static slot indicating the address family simplifies
code which wants to map a socket address to its
family.
* lisplib.c (sock_instantiate): Call sock_load_init
before loading socket.tl rather than after, because socket.tl
now references variables defined inside sock_load_init.
* share/txr/stdlib/socket.tl (sockaddr, sockaddr-in,
sockaddr-in6, sockaddr-un): New static slot, family.
* txr.1: Documented family slots.
