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.

domain, pribus (the primary bus, eg the bus that this chip is on),
secbus (the secondary bus, eg the bus immediately behind this chip)
and subbus (the number of the highest bus behind this chip).
Normally, this information is reported via bootverbose parameters, but
that's hard to use for debugging in some cases.
This adds reading of pribus to make this happen. In addition, change
the narrow types to u_int to allow for easier reporting via sysctl for
domain, secbus and subbus. This should have no effect, but if it
does, please let me know.

When ip6_savecontrol_v4() is called from ip6_savecontrol() we
were not passing back the **mp thus the information will be missing
in userland.
Istead of going with a *** as suggested in the PR we are returning
**mp now and passing in the v4only flag as a pointer argument.

no longer needs local patching to be usable for those types. For now
I've set the variables in /etc/defaults/rc.conf to the previous defaults

Now we have a single /dev/snp device node, which can be opened by
watch(8) multiple times. Even though snp(4) will be dead as of next
week, it's nice having this in SVN, because:
- We may want to MFC it to RELENG_7.
- By the time we fix snp(4) again, it's already there, existing watch(8)
binaries should already work.
Just like bpf(4), I'm adding a symlink from snp0 to snp to remain binary
compatible.
This can be used to disable the 80pin cable check on systems which forget to
set the bit -- such as certain laptops and Soekris boards.

detect whether the integer division table is large enough to handle the
divisor. Before this change, the last two table elements were never used,
thus causing the slow path to be used for those divisors.
- Speedup the lock orderings lookup modifying the witness graph from a
linked tree to a matrix. A table lookup caches the lock orderings in
order to make a O(1) access for them. Any witness object has an unique
index withing this lookup cache table.
- Reduce the lock contention on w_mtx acquiring it only when the LOR
actually happens and not in a sane case. In order to do this don't totally
flush lock lists (per-CPU spinlocks list and per-thread sleeplocks list)
but check for ll_count anytime we need to have to verify allocations sanity.
- Introduce the function witness_thread_exit() in the witness namespace which
should verify a thread doesn't hold any witness occurrence why exiting.
- Rename the sysctl debug.witness.graphs into debug.witness.fullgraph and
add debug.witness.badstacks which prints out stacks for LOR revealed.
This is implemented using the stack(9) support, which makes WITNESS to be
dependent by the STACK option or by the DDB (including STACK) option.
- Fix style(9) for src/sys/kern/subr_witness.c

bpf(4) now uses cdevpriv to distinguish multiple file descriptors, where
it used to be implemented using device cloning. Ports like libpcap
properly detect the change in their configure scripts, but it doesn't
hurt to increase __FreeBSD_version.
While there, change the bpf(4) manual page to refer to /dev/bpf instead
of /dev/bpfN.
