vt(4): Implement basic support for KDSETMODE ioctl

With the current implementation, this allows an X11 server to tell
the console it switches a particular window in "graphics mode". This
information is used by the mouse handling code to ignore sysmouse events
in the window taken by the X server: only him should receive those
events.

vt(4): Add cngrab() and cnungrab() callbacks

They are used when a panic occurs or when entering a DDB session for
instance.

cngrab() forces a vt-switch to the console window, no matter if the
original window is another terminal or an X session. However, cnungrab()
doesn't vt-switch back to the original window currently.

drm: Don't "taskqueue" vt-switch if under DDB/panic situation

If DDB is active, we can't use a taskqueue thread to switch away from
the X window, because this thread can't run.

vt(4): Pause the vt_flush() timer when the screen is up-to-date

The timer is restarted whenever a window buffer is marked as dirty or
the mouse cursor moves.

There's still room for improvement. For instance, we should not mark a
window buffer as dirty when this window isn't displayed.

vt(4): Fix mouse cursor handling in vt_fb/creator_vt/ofwfb

There were two issues:
    1. The area given to vt_is_cursor_in_area() was adding the drawable
       area offset, something already handled by this function.
    2. The cursor was shifted on the screen by the offset of this area
       and thus was misplaced or not erased. Furthermore, when reaching
       the bottom or right borders, the cursor was either totally
       removed or not erased correctly.

valid).

add scripts for generating a diff from p4...

awkdiff is the script from scottl that he got from ken a long time

This does simple massaging of p4 output to create a useful diff...

The script p4diffbranch will create a diff that includes new and

for extracting patches from p4...  It does take a changeset that will
