(a) remove the pointer to each driver's tty structure array from cdevsw

(b) add a function callback vector to tty drivers that will return a pointer
    to a valid tty structure based upon a dev_t
(c) make syscons structures the same size whether or not APM is enabled so
    utilities don't crash if NAPM changes (and make the damn kernel compile!)
(d) rewrite /dev/snp ioctl interface so that it is device driver and i386
    independant
