Modified files:
	lib/libc/net   : freeaddrinfo.c 

Log message:
don't permit freeaddrinfo(NULL).  now the behavior is consistent
across {free,net,open}bsd.

both rfc2553 and X/Open spec are silent about the behavior,
and there's no strong consensus either.  i think library should NOT be
forgiving in this case, to promote development of more robust 3rd-party
codebase (code works on "freeaddrinfo(NULL) = SEGV" will work on
"freeaddrinfo(NULL) is okay" environment, but not the other way around).
only issue i have now is NRL freeaddrinfo() compatibility, which permits
freeaddrinfo(NULL).
