pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2 (UCB copyrighted).

have sys/net/route.c:rtrequest1(), which takes rt_addrinfo * as the argument.
pass rt_addrinfo all the way down to rtrequest, and ifa->ifa_rtrequest.
3rd arg of ifa->ifa_rtrequest is now rt_addrinfo * instead of sockaddr *
(almost noone is using it anyways).

benefit: the follwoing command now works.  previously we need two route(8)
invocations, "add" then "change".
# route add -inet6 default ::1 -ifp gif0

remove unsafe typecast in rtrequest(), from rtentry * to sockaddr *.  it was
introduced by 4.3BSD-reno and never corrected.

XXX is eon_rtrequest() change correct regarding to 3rd arg?
eon_rtrequest() and rtrequest() were incorrect since 4.3BSD-reno,
so i do not have correct answer in the source code.
someone with more clue about netiso-over-ip, please help.
