related cleanups:
- Require each driver to initalize a mutex in the scsi_low_softc that
is shared with the scsi_low code. This mutex is used for CAM SIMs,
timers, and interrupt handlers.
- Replace the osdep function switch with direct calls to the relevant
CAM functions and direct manipulation of timers via callout(9).
- Collapse the CAM-specific scsi_low_osdep_interface substructure
directly into scsi_low_softc.
- Use bus_*() instead of bus_space_*().
- Return BUS_PROBE_DEFAULT from probe routines instead of 0.
- No need to zero softcs.
- Pass 0ul and ~0ul instead of 0 and ~0 to bus_alloc_resource().
- Spell "dettach" as "detach".
- Remove unused 'dvname' variables.
- De-spl().
Tested by: no one
- Add a per-softc mutex as a driver lock.
- Use callout(9) instead of timeout(9).
- Set softc pointer in si_drv1 of cdev instead of looking softc
up via devclass in cdev methods.
Tested by: no one
- Don't recurse driver mutex.
- Don't hold driver mutex across fubyte/subyte.
- Replace fubyte/subyte loops with copyin/copyout calls.
- Use relatively sane locking in wl_ioctl().
- Use bus space accessors instead of in*()/out*().
- Use callout(9) instead of timeout(9).
- Stop watchdog timer in detach and don't hold mutex across
bus_teardown_intr().
- Use device_printf() and if_printf().
- De-spl().

Without this fix, the vnet was NULL and would crash.
This fix is similar to what was done inside the ioctl handler for PF.
Tested by:
(1) Boot a kernel with "options VIMAGE" enabled
(2) Type:
echo "map lo0 from 10.0.0.0/24 to ! 10.0.0.0/24 -> 127.0.0.1/32" > /etc/ipnat.rules ; service ipnat onerestart

Summary:
Currently if there are problems finding a symbol, backtrace ends up printing
something like:
0xdeadbeef: at +0x12345
Which is pretty useless. This on its own should be fixed (retrieving symbols),
but aside from that, using db_printsym() is a better solution anyway. If it
can't find a valid symbol it prints the actual address, and it has the added
benefit that if it can find the symbol, it might be able to print the file and
line as well.

Early UART should be released right after system console initialization is
completed. Otherwise, after cninit() both early and system console coexist
what may lead to various issues (i.a. writing to unmapped early
UART address). This cannot be done in cninit_finish() since it can be
called late at the end of MI configuration.

OpenBSD; unsure why we chose to do so. As groups are a requirement for
pf, exposing them by default will make our pf implementation less
confusing.
While here add a missing free() that OpenBSD fixed 7 years ago.
