Further reduce diffs with OpenBSD's arc4random. The main functional

OpenBSD's fix introduces some additional overhead in the form of a

The only significant remaining difference between our arc4random and

When the kernel is running in a virtual machine, it cannot rely upon the
processor family to determine if the workaround for AMD Family 10h Erratum
383 should be enabled. To enable virtual machine migration among a
heterogeneous collection of physical machines, the hypervisor may have
been configured to report an older processor family with a reduced feature
set. Effectively, the reported processor family and its features are like
a "least common denominator" for the collection of machines.
Therefore, when the kernel is running in a virtual machine, instead of
relying upon the processor family, we now test for features that prove
that the underlying processor is not affected by the erratum. (The
features that we test for are unlikely to ever be emulated in software
on an affected physical processor.)

Remove multilevel freezing mechanism, implemented to handle specifics of
the ATA/SATA error recovery, when post-reset recovery commands should be
allocated when queues are already full of payload requests. Instead of
removing frozen CCBs with specified range of priorities from the queue
to provide free openings, use simple hack, allowing explicit CCBs over-
allocation for requests with priority higher (numerically lower) then
CAM_PRIORITY_OOB threshold.
Simplify CCB allocation logic by removing SIM-level allocation queue.
After that SIM-level queue manages only CCBs execution, while allocation
logic is localized within each single device.

Change CCB queue resize logic to be able safely handle overallocations:
- (re)allocate queue space in power of 2 chunks with 64 elements minimum

- automatically reallocate the queue to double size if it is overflowed.
- if queue reallocation failed, store extra CCBs in unsorted TAILQ,
fetching them back as soon as some queue element is freed.
To free space in CCB for TAILQ linking, change highpowerq from keeping
high-power CCBs to keeping devices frozen due to high-power CCBs.
This encloses all pieces of queue resize logic inside of cam_queue.[ch],
removing some not obvious duties from xpt_release_ccb().

Don't pass a timeout of 0 ticks to pause() for a delay of less than 1
hz tick. On 8.x this results in an infinite sleep as pause() does not
support a delay of 0 ticks. Since all delay values are converted from
nanoseconds to ticks using a floor function, skipping the sleep for a
delay smaller than 1 tick is the more consistent than rounding up to a
single tick.
