rt_check_fib() can go away (as can its evil twin in_rt_check()).

Payload Length) as set in tcpip_fillheaders().
ip6_output() will calculate it based of the length from the
mbuf packet header itself.
So initialize the value in tcpip_fillheaders() in correct
(network) byte order.
With the above change, to my reading, all places calling tcp_trace()
pass in the ip6 header via ipgen as serialized in the mbuf and with
ip6_plen in network byte order.
Thus convert the IPv6 payload length to host byte order before printing.

Merge tcp_mss_update() with code from tcp_mtudisc() basically
doing the same thing.
This gives us one central place where we calcuate and check mss values
to update t_maxopd (maximum mss + options length) instead of two slightly
different but almost equal implementations to maintain.

virtualization work done by Marko Zec (zec@).
This is the first in a series of commits over the course
of the next few weeks.
Mark all uses of global variables to be virtualized
with a V_ prefix.
Use macros to map them back to their global names for
now, so this is a NOP change only.
We hope to have caught at least 85-90% of what is needed
so we do not invalidate a lot of outstanding patches again.
