Ah, this is something I forgot about.  There are existing ioctl interfaces
for this on Linux and BSD (linux/vt.h, sys/consio.h) that are almost the
same on the two platforms.  So we might as well do something that is at
least mostly source-compatible with that.  These basically give ways to
synchronize with the vt switching and disable the console driver's hot keys
so the X server can know when it's safe to access the video hardware
directly and restore it to its prior state when a switch is requested.
