Pull up following revision(s) (requested by ragge in ticket #655):
        sys/arch/vax/boot/boot/devopen.c: 1.19-1.20
        sys/arch/vax/boot/boot/hp.c: 1.11
        sys/arch/vax/boot/boot/if_de.c: 1.10
        sys/arch/vax/boot/boot/if_qe.c: 1.10
        sys/arch/vax/boot/boot/ra.c: 1.21-1.22
        sys/arch/vax/boot/boot/vaxstand.h: 1.10
Use a common routine ubmap() that setup the map registers as needed,
not expecting everything to be below 4M.  This solves the problem
that large kernels cannot be loaded reported on port-vax.
--
Change the driver to map the data structures onto the qbus.
--
Fix bug causing autoboot on 750/780 not to work.  Cleanup.
