Sending a window update from soreceive() results in a lock reversal.

debugging if this case were to happen.

correct open/close behaviour of filesystems:
When an ioctl to modify the MBR arrives, we cannot take for granted that
we have the consumer open.
The symptom is that one cannot run 'boot0cfg -s2 /dev/ad0' in single-user
mode because / is the only open partition in only open r1w0e1.
If it is not, we attempt to increase the write count by one and
decrease it again afterwards.
Presumably most if not all other slices suffer from the same problem.

the address of a channel on a SCC, it returns 0 on failure. [1]
- Hardcode channel 1 for the keyboard on Z8530, the information present
in the Open Firmware device tree doesn't allow to determine this via
uart_cpu_channel(). This makes the keyboard (if one backs out rev. 1.5
of sys/dev/puc/puc_sbus.c and has both keyboard and mouse plugged in to
avoid the hang that revision works around) and consequently syscons(4)
on Ultra 2 work. There's a problem with the keyboard LEDs similar to
the one on Ultra 60 (LEDs don't get lit under X) though, instead of
lighting just a specific single one all get lit and can't be turned off
again. [1]
- Add comments about what uart_cpu_channel() and uart_cpu_getdev_keyboard()
do and their constraints.
- Improve the comments about what uart_cpu_getdev_[console,dbgport]() do,
they don't return an address (as in bus) but an Open Firmware package
handle.

instead acquire it conditionally in closef() if it is required for
advisory locking. This removes Giant from the close() path of sockets
and pipes (and any other objects that don't acquire Giant in their
fo_close path, such as kqueues). Giant will still be acquired twice for
vnodes -- once for advisory lock teardown, and a second time in the
fo_close method. Both Poul-Henning and I believe that the advisory lock
teardown code can be moved into the vn_closefile path shortly.
This trims a percent or two off the cost of most non-vnode close
operations on SMP, but has a fairly minimal impact on UP where the cost
of a single mutex operation is pretty low.
