don't inline the locking primitives, and only grab those parts of mii
that we really need. Other space optimizations are too agressive for
the generic file (removing all of usb, and loading it as kernel
modules).
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.

As a consequence we may now get an unexpected result(*).

there was a bug, noone was definitively sure.

This is different to the first one (as len gets updated between those
two) and would have caught various edge cases (read bugs) at a well
defined place I had been debugging the last months instead of
triggering (random) panics further down the call graph.

logic here gets a little complex, but the net effect is that the
SECURE_SYMLINKS flag will prevent us from ever following a symlink.
Without it, we'll only follow symlinks to dirs. bsdtar specifies
SECURE_SYMLINKS by default, suppresses it for -P.
I've also beefed up the write_disk_secure test to verify this
behavior.

other a expected to use sysctl (as discussed on net@).
