MFC rev.188571
Clarify and reimplement the bioq API so that bioq_disksort() has
the correct behaviour (sorting by distance from the current head position
in the scan direction) and bioq_insert_head() and bioq_insert_tail()
have a well defined (and useful) behaviour, especially when intermixed
with calls to bioq_disksort().
See the original commit log for more details.
NO API/ABI changes (except from fixing bugs and defining
unspecified behaviour that no code should rely on).

Disable INTx when enabling MSI/MSIX
This addresses interrupt storms that were noticed after enabling MSI
in drm. I think this is due to a loose interpretation of the PCI 2.3
spec, which states that a function using MSI is prohibitted from using
INTx. It appears that some vendors interpretted that to mean that they
should handle it in hardware, while others felt it was the drivers
responsibility.
This fix will also likely resolve interrupt storm related issues with
devices other than drm.

Extend the management of PCIM_CMD_INTxDIS.
We now explicitly enable INTx during bus_setup_intr() if it is needed.
Several of the ata drivers were managing this bit internally. This is
better handled in pci and it should work for all drivers now.
We also mask INTx during bus_teardown_intr() by setting this bit.

of da(4) and cd(4) peripheral devices to not hold locks when freeing the

- vm.stats.(sys|vm).*
- sysctl.name2oid

Other changes:
- Remove GIANT_REQUIRED from vmtotal().

Initialize the vblank structures at load time. Previously we did this
at irq install/uninstall time, but when we vt switch, we uninstall the
irq handler. When the irq handler is reinstalled, the modeset ioctl
happens first. The modeset ioctl is supposed to tell us that we can
disable vblank interrupts if there are no active consumers. This will
fail after a vt switch until another modeset ioctl is called via dpms
or xrandr. Leading to cases where either interrupts are on and can't
be disabled, or worse, no interrupts at all.

MFC r189283:
Correct types of variables used to track amount of allocated SysV shared
memory from int to size_t. Implement a workaround for current ABI not
allowing to properly save size for and report more then 2GB sized segment

UPDATING note for limitations of this temporal solution.

Disable the vm_page_startup assertion for now. It always fails on
platforms with superpages currently because the pages used by
vm_reserv_startup() are incorrectly included in the 'npages' count. I
haven't removed the assertion as I think this is a real bug, but the side
effect is just that some memory is wasted on never-used vm_page structures.
The assertion was removed from HEAD which is why the bug wasn't noticed
there (and thus this is a direct commit to 7).

Ensure that the semaphore value is re-checked after sem_lock
is re-acquired, after the condition variable is signalled.
Early MFC, as the test case in the PR is fairly complete and the
submitter also re-ran test case on -STABLE. It also bites Python
fairly hard, which will otherwise try to use POSIX sems for its
internal thread synchronization; this needs more in-depth testing.
