Add in support for timing out IPv4 routes added due to redirects,

KAME had already added this functionality to the IPv6 stack, so
I followed their example in adding the sysctl variables
net.inet.icmp.rediraccept and net.inet.icmp.redirtimeout.

Change the way receive idle time and round trip time are measured.
...
Instead of incrementing t_idle and t_rtt in tcp_slowtimo(), we now
take a timstamp (via tcp_now) and use subtraction to compute the
delta when we actually need it (using unsigned arithmetic so that
tcp_now wrapping is handled correctly).
Based on similar changes in FreeBSD.

better support for multiple IPv4 addresses on a single interface.
...
- consider non-primary (2nd and beyond) IPv4 address as "local", and prevent
outgoing ARP.
- for routing entries generated by ARP, make sure to set rt->rt_ifa equal to
rt_key, to help IPv4 source address selection for traffic to myself.
PR 13311.
caveats/TODOs:
- interface routes ("connected routes" in cisco terminlogy) is tied with the
primary (1st) IPv4 address on the interface. should be fixed with updates
to rt_ifinit().
- source address selection for offlink locations. 1st address tend to be used
with the current code
(you can configure it right by setting rt->rt_ifa accordingly).
