... not just the visible part.
This fixes a bug where, when switching from eg. vt_vga to vt_fb (ie. the
resolution goes up), the originally hidden, uninitialized area of the
buffer is displayed on the screen. This leads to a missing text cursor
when it's over an unitialized area.
This was also visible when selecting text: the uninitialized area was
not highlighted.
Internally, this area was zeroed: characters were all 0x00000000,
meaning the foreground and background color was black. Now, everything
is filled with a space with a gray foreground color, like the visible
area.
While here, remove the check for the mute flag and always use
TERMINAL_NORM_ATTR as the character attribute (ie. gray foreground,
black background).

"vm_paging_target() > 0" was a reasonable way of determining if the
inactive queue scan met its target. However, now that other threads
can be allocating pages while the inactive queue scan is running, it's
an unreliable method. The effect of it being unreliable is that we
can start swapping out processes when we didn't intend to.
This issue has existed since the kernel was multithreaded, but the
changes to the inactive queue target in 10.0-RELEASE have made its
effects visible.
This change introduces a more direct method for determining if the
inactive queue scan met its target that is not affected by the actions
of other threads.

This fixes a "General protection fault" in vt_vga, where
vt_is_cursor_in_area() erroneously reported that the cursor was over the
text. This led to negative integers stored in "unsigned int" and chaos.

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.
