1. vt ioctl to get new vt requested by change_console?

Would anyone consider this patch? I don't know how else to get this info
from a user program.  I want to use VT_RELDISP ioctl to say it's not ok
to do a VT switch, based on which VT was requested for activation.  This
information is not otherwise available.
