need to reassign the vp->v_op to devfs_specops, we know that is the

Only use the current value if there's one IRQ. Some systems return
multiple IRQs (which is nonsense for _CRS) when the link hasn't been
programmed. Before, this was a KASSERT. A ServerWorks system was
seen returning IRQs of 0, 2 in response to _CRS before link setup.
Thanks to sam@ for quick testing and turnaround on this.

Only report a critical battery level once until it's gone non-critical.
An improvement would be to check all batteries for critical state before
printing a message.
- Argument 'flags' in g_mirror_destroy_consumer() function is unsed -
mark it as such.
- Before closing consumer check if it is open. It can be closed here
when g_mirror_connect_disk() fails on g_access().
Keeping consumers open when device is closed is very hard. We need to
open consumers sometimes to update metadata, etc.
Many hacks was introduced in the past to made it possible. You cannot
be sure that you can open consumer for writing always, even if you think
it should be allowed. If one of the mirror components is for example da0
and you try to open it, you can get EPERM when da0s1 is opened for reading
(because BSD class opens consumers (da0) with an extra 'e' bit set).
Waiting for the events queue to be empty may do the trick, but it makes
code much uglier (as you cannot always call g_waitidle()), it doesn't
solve all edge cases and it can introduce deadlocks if there are events
in the queue that wait for gmirror.
I removed those hacks. Now all consumers are open r1w1e1 always, even if
device is closed. Maybe it is less clean from GEOM perspective, but simpify
code a lot and make it much more reliable.
The only issue was retaste event which is sent when we close consumers
opened for writing. I ignore retaste event by not detaching consumer
immediately (so retaste event is not send to my class) and sending event
right after it to detach and destroy consumer.

Initialise init_addr in pf_map_addr() in the PF_POOL_ROUNDROBIN,
prevents a possible endless loop in pf_get_sport() with 'static-port'
ICMP state entries use the ICMP ID as port for the unique state key. When
checking for a usable key, construct the key in the same way. Otherwise,
a colliding key might be missed or a state insertion might be refused even
though it could be inserted. The second case triggers the endless loop,
possibly allowing a NATed LAN client to lock up the kernel.

Move launching the worker thread from a SYSINIT to the first device's

hardware always had a worker thread running.
Call umask() before opening the lock-file for a queue, to make sure
the file will be created with the right access, if the call to open()
does create it. Also fix the other call to umask() to turn off

Use a generic way to back threads out of wait queues when handling
signals instead of having more intricate knowledge of thread state
within signal handling.
Simplify signal code because of above (by David Xu).
Use macros for libpthread usage of pthread_cleanup_push() and
pthread_cleanup_pop(). This removes some instances of malloc()
and free() from the semaphore and pthread_once() implementations.
When single threaded and forking(), make sure that the current
thread's signal mask is inherited by the forked thread.
Use private mutexes for libc and libpthread. Signals are
deferred while threads hold private mutexes. This fix also

1. make umtx sharable between processes, the way is two or more processes
call mmap() to create a shared space, and then initialize umtx on it,
after that, each thread in different processes can use the umtx same
as threads in same process.
2. introduce a new syscall _umtx_op to support timed lock and condition
variable semantics. also, orignal umtx_lock and umtx_unlock inline
functions now are reimplemented by using _umtx_op, the _umtx_op can
use arbitrary id not just a thread id.

Fix wep operation for station mode:
o don't encapsulate on tx; the chip expect a raw frame w/o the crypto header
o clear the WEP bit in the 802.11 header on rx so the 802.11 layer doesn't
try to strip the crypto header
o clobber the "drop unencoded frames" state bit when privacy is enabled so
rx'd frames we pass up to the 802.11 layer are not discarded as unencrypted

When printing a data file received from some other host, check to make
sure the data file has been completely transfered before starting to
print it. This is needed because some implementations of lpr will send
the control-file for a print job before sending the matching data-files,
and that can cause problems if the receiving host is a busy print-server.
