MFC: r241028

Change queue overflow checks from DIAGNOSTIC+panic() to KASSERT() to make
them enabled on HEAD by default. It is probably better to do single compare
then hunt for unexpected memory corruption.

MFC: r241444

Increase device CCB queue array size by CAM_RL_VALUES - 1 (4) elements.
It is required to store extra recovery requests in case of bus resets.
On ATA/SATA this fixes assertion panics on HEAD with INVARIANTS enabled or
possible memory corruptions otherwise if timeout/reset happens when device
CCB queue is already full.

MFC: r249466 (partial), r249438, r249481, r250025 (partial)

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.

MFC: r253958

Change CCB queue resize logic to be able safely handle overallocations:
 - (re)allocate queue space in power of 2 chunks with 64 elements minimum
and never shrink it; with only 4/8 bytes per element size is insignificant.
 - 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().

Merge r133175 from upstream:

2008-03-13  Dennis Czeremin  <dennis.czeremin@smiths-heimann.com>

	PR libstdc++/35566
	* include/bits/stl_multimap.h (multimap<>::multimap(_InputIterator,
	_InputIterator)): Forward to _M_insert_equal, not _M_insert_unique.

This patch was GPL2 at the time and fixes a regression introduced with
the merge of GCC r129013 in FreeBSD r236829 (merged to stable/8 in r237508).

MFC r262338
  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.)
