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.

two) and would have caught various edge cases (read bugs) at a well

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.

As discussed with Robert on IRC, checking the permissions on
/dev/console to see if we can call TIOCCONS could be unreliable. When we
run a chroot() without a devfs instance mounted inside, it won't
actually check the permissions on the device node inside the devfs
instance.
Using the already existing PRIV_TTY_CONSOLE for this seems like a better
idea.

Initially, 'acl' (an 'acl_t *') is allocated, and its ACCESS_ACL and
DEFAULT_ACL fields are passed to the 'libc' ACL routines for subsequent
allocation. If the '-m' option (merge existing ACL with a new one) is
specified, then 'set_acl_mask()' will be called and passed one of the
two ACLs. This function, in turn, replaces this given ACL structure by
another, freshly allocated. However, the pointer in the 'acl' variable
in the caller is not updated. The caller then proceeds to free the ACL,
incurring in a double free condition.
