add opregion handling for drm2 - which exposes some ACPI video configuration
pieces that some Lenovo laptop models use to flesh out which video device
to speak to. This enables the brightness control in ACPI to work these models.
The CADL bits are also important - it's used to figure out which ACPI
events to hook the brightness buttons into. It doesn't yet seem to work
for me, but it does for the OP.
Tested:
* Lenovo X230 (mine)
* OP: ASUS UX51VZ

tunables to modify the default cpu topology advertised by bhyve.
Also add a tunable "hw.vmm.topology.cpuid_leaf_b" to disable the CPUID
leaf 0xb. This is intended for testing guest behavior when it falls back
on using CPUID leaf 0x4 to deduce CPU topology.
The default behavior is to advertise each vcpu as a core in a separate soket.
the vcpu had no caches at all. This causes problems when executing applications
in the guest compiled with the Intel compiler.

to get upset.
The Qualcomm Atheros reference design code goes through significant
hacks to shut down RX before TX. It doesn't even try do do it in the
driver - it actually makes the DMA stop routines in the HAL shut down
RX before shutting down TX.
So, to make this work for chips that aren't the AR9380 and later, do
it in the driver. Shuffle the TX stop/drain HAL calls to be called
*after* the RX stop HAL call.
Tested:
* AR5413 (STA)
* AR5212 (STA)
* AR5416 (STA)
* AR9380 (STA)
* AR9331 (AP)
* AR9341 (AP)

There were situations where the cursor was not erased/redrawn or its
position was marked as dirty even though it's not displayed. The code is
now more straightforward.
At the same, add a function to determine if the cursor covers a given
area. This is used by backends to know if they need to draw the cursor.
This new function should be paired with a new state in struct vt_device,
called vd_mshown, which indicates if the cursor should be displayed.
This again simplifies vd_bitblt_text_t callback's API.

In textmode, no font is loaded, thus the page fault in
vt_mark_mouse_position_as_dirty() when it wants the font width/height.
For now, create a fake area for the textmode. This needs to be modified
if vt_vga gains mouse support in textmode.
While here, fix a build failure when SC_NO_CUTPASTE is defined:
vt_mark_mouse_position_as_dirty() must not be included in this case.
