Another round of updates. Highlights:

Browse Source 
(1) Merged i386/i386/sb.h, deleted pc98/pc98/sb.h.

(2) pc98/conf/GENERIC8 looks more like i386/conf/GENERIC now.

(3) Fixed display bug in pc98/boot/biosboot/io.c.

(4) Prepare to merge memory allocation routines:

	pc98/i386/locore.s
	pc98/i386/machdep.c
	pc98/pc98/pc98_machdep.c
	pc98/pc98/pc98_machdep.h

(5) Support new board "C-NET(98)":

	pc98/pc98/if_ed98.h
	pc98/pc98/if_ed.c

(6) Make sure FPU is recognized for non-Intel CPUs:

	pc98/pc98/npx.c

(7) Do not expect bss to be zero-allocated:

	pc98/pc98/pc98.c
