Try to make the MBUF_FRAG_TEST code work better.
- Don't try to fragment the packet if it's smaller than mbuf_frag_size.
- Preserve the size of the mbuf chain which is modified by m_split().
- Check that m_split() didn't return NULL.
- Make it so we don't end up with two M_PKTHDR mbuf in the chain.
- Use m->m_pkthdr.len instead of m->m_len so that we fragment the whole
chain and not just the first mbuf.
- Fix a nearby style bug and rework the logic of the loops so that it's
more clear.
This is still not quite right, because we're clearly abusing m_split() to
do something it was not designed for, but at least it works now. We
should probably move this code into a m_fragment() function when it's
correct.

Once ppp session is over, the route to ff02::tun0/32 was
deleted, and never came back. Now, the route to
ff02::tun0/32 is installed at the end of IPV6CP negitiaton.

Add code to implement two new USB quirk types: NO_INQUIRY and NO_INQUIRY_EVPD
The former fakes a valid response to an inquiry command. (I am completely
blown away that there are devices which hang upon receiving inquiry). The
latter returns "invalid request" to any inquiry commands with EVPD set.
NO_INQUIRY implies NO_INQUIRY_EVPD but not vice versa. Both quirks have been
tested separately on my USB key although it didn't require either of them.
While I'm here, fix wildcarding so that any/all of vendor, product, revision
can be wildcarded.

Since ppp.link{up,down} is invoked at the end of IPCP negotiation, if
we need ppp.link{up,down}, we couldn't disable IPCP. Now, if IPCP is
disabled, ppp.link{up,down} is invoked at the end of IPV6CP
negotiation.

Add the MBUF_FRAG_TEST option. When compiled in, this option
allows you to tell ip_output to fragment all outgoing packets
into mbuf fragments of size net.inet.ip.mbuf_frag_size bytes.
This is an excellent way to test if network drivers can properly
handle long mbuf chains being passed to them.
net.inet.ip.mbuf_frag_size defaults to 0 (no fragmentation)
so that you can at least boot before your network driver dies. :)

Expand scope of the MLS policy to include a new entry point available
for enforcement:
mac_mls_check_system_swapon() - Require that the subject and the
swapfile target vnode labels dominate one another. An additional
check is probably needed here to require that the swapfile target
has a label of mls/high to prevent information leakage through
swapfiles.

- Add vm_paddr_t, a physical address type. This is required for systems
where physical addresses larger than virtual addresses, such as i386s
with PAE.
- Use this to represent physical addresses in the MI vm system and in the
i386 pmap code. This also changes the paddr parameter to d_mmap_t.
- Fix printf formats to handle physical addresses >4G in the i386 memory
detection code, and due to kvtop returning vm_paddr_t instead of u_long.
Note that this is a name change only; vm_paddr_t is still the same as
vm_offset_t on all currently supported platforms.

Replace the at_fork, at_exec, and at_exit functions with the slightly more
flexible process_fork, process_exec, and process_exit eventhandlers. This
reduces code duplication and also means that I don't have to go duplicate
the eventhandler locking three more times for each of at_fork, at_exec, and
at_exit.

- Remove witness_dead and just use witness_watch instead. If witness_watch
is set to 0, it now has the same affect as setting witness_dead used to
have.
- Added a sysctl handler that allows root to change witness_watch from a
non-zero value to zero to disable witness at runtime. Note that you
can't turn witness back on once it is off. You can only turn it off as
a one-way switch.
- Added a comment describing the possible values of witness_watch.

Don't call sysbeep() in sc_bell() if either duration or pitch is zero.
Otherwise sysbeep() makes an annoying clicking sound on some systems.
'kbdcontrol -b off' just sets the duration and pitch to zero, it doesn't
set the QUIET_BELL flag.
