Diff reduction against stable/9: this is a pure mechanical comment
change that eliminates the unwanted diff caused by different
Pod::Simple version and have no runtime impact.
We do this in the hope of minimizing variants of patches that would
need to be published, should an update is required during the
remaining lifetime of the stable/8 branch.

Correct a series of errors in the hand-rolled locking for drace_debug.c:
- Use spinlock_enter()/spinlock_exit() to prevent a thread holding a
debug lock from being preempted to prevent other threads waiting
on that lock from starvation.
- Handle the possibility of CPU migration in between the fetch of curcpu
and the call to spinlock_enter() by saving curcpu in a local variable.
- Use memory barriers to prevent reordering of loads and stores of the
data protected by the lock outside of the critical section
- Eliminate false sharing of the locks by moving them into the structures
that they protect and aligning them to a cacheline boundary.
- Record the owning thread in the lock to make debugging future problems
easier.

Ensure that all cases that enqueue a netgraph item for delivery by a
ngthread properly set the item's depth to 1. In particular, prior to this
change if ng_snd_item failed to acquire a lock on a node, the item's depth
would not be set at all. This fix ensures that the error code from rcvmsg/
rcvdata is properly passed back to the apply callback. For example, this
fixes a bug where an error from rcvmsg/rcvdata would not previously
propagate back to a libnetgraph consumer when the message was queued.

Some aac(4) adapters will always report that a direct access device is
offline in response to a INQUIRY command that does not retreive vital
product data(I personally have observed the behaviour on an Adaptec 2405
and a 5805). Force the peripheral qualifier to "connected" so that upper
layers correctly recognize that a disk is present.
This bug was uncovered by r216236. Prior to that fix, aac(4) was
accidentally clearing the peripheral qualifier for all inquiry commands.
This fixes an issue where passthrough devices were not created for
disks behind aac(4) controllers suffering from the bug. I have
verified that if a disk is not present that we still properly detect
that and not create the passthrough device.

- Apparently, r186520 was just wrong and the clock of Oxford OX16PCI958 is
neither DEFAULT_RCLK * 2 nor DEFAULT_RCLK * 10 but plain DEFAULT_RCLK
and there's no (open) source indicating otherwise. This was tested with
an EXSYS EX-41098-2, whose clock is not configurable and identifies as:
puc0@pci0:5:1:0: class=0x070200 card=0x06711415 chip=0x95381415 rev=0x01 hdr=0x00
vendor = 'Oxford Semiconductor Ltd'
class = simple comms
subclass = multiport serial
Note that this exactly matches the card mentioned in PR 129665 so no
sub-device/sub-vendor based quirking of the latter is possible. So maybe
we should grow some sort of tunable, in case non-default cards such as
the latter aren't configurable either (this also wouldn't be the first
time an allegedly tested commit turns out to be wrong though).
